- There is many opinions on tools but for me the torque wrench is an absolute garage essential. Here’s me explaining what a torque wrench is, how to you use a torque wrench, what to think about when buying a torque wrench, digital torque wrench verse click... plus a few things from my experience. This is a great video to understand the best torque wrench for motorcycles and for a Teng Tools review on their torque wrenches.
I want to highlight that I am no pro mechanic, I am a home learned, trial and error, and learning as I go. I’d love to hear you’re thoughts on torque wrenches? Let me know in the comments!
I use Teng Tools Torque Wrenches and highly rate them: www.tengtools....
What is a torque wrench?
A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw. It is usually in the form of a socket wrench with special internal mechanisms.
Using Nm you can apply a specific force to tighten something.
In simpler terms white knuckling bolts might be possible when you’ve been in the industry 30 years but for most knowing the 8th of a turn to tighten too is a mysterious game that can have expensive consequences… I’ve cracked clutch houses, split cases and ruptured a nut cap [show it], I’ve even had a trailer wheel fall off when the wheel nut came loose.
The good news is this is all avoidable with the right tools - torque wrench.
Torque wrenches enable you to tighten to manufacturer specifications, and is especially important on light metals like aluminium that can scratch and dent easily. Torque wrenches can also be used to set bolt pulleys, bearings, seal the mating surface between a gasket or crush plate, and more. In short it enables proper tension and loading of all parts
Types
Digital - more accurate but can run out of battery - 1% accuracy to ISO standards
Mechanical - 4% accuracy to ISO standards
Wrenches start at 1Nm and go up to 980Nm, you can also get screw drivers
Tend to come in ¼”,3/8”,1/2” & ¾” sq drives
While a torque wrench is not absolutely required, it's a good idea. You need to ensure the wheel is evenly clamped onto the hub. This prevents the wheel from warping and causing other issues.
Features of torque wrenches
measurement in Nm - this is N [force x gravity] - 10 N is roughly 1kg at 1m - this - linear measurement - so 10N is roughly 2kg and 2m
Flip reverse switch (reverse not for Torque setting)
Designed to Torque right hand (clockwise) fasteners or left hand but some you can reverse the setting on
Things to think about
Any reverse bolts? Which direction do I need to torque?
What range of torque settings to you need?
Can you use socket adapters to extend the usage?
Re-calibration of torque wrenches is needed, depending on the brand you’re looking at every 12 months or xx amount of cycles - Teng do this in house
ISO 6789 : 2003 will ensuring the tool calibration complies with the best set up.
Each torque wrench should come with a calibration certificate
This is the first in a mini series on garage life - keeping myself busy in lock-down. Let me know what you think, do you use torque wrenches? And also, are there any garage topics you would like me to cover?

As a mechanic with over 40 years hands on it's nice to see a youngster that understands torque wrenches and their purpose rather than just going FT.
thanks Phil 😃
That was a decent overview of torque wrenches. After purchasing a few coin cell operated tools for the garage, such as an air pressure gauge, caliper, etcetera...I have now replaced them with mechanical only equivalents. It doesn't help that for nearly half of the year, temperatures drop below freezing, and the batteries seem to always be dead.
Ah I hear you there. I had a digital one and it was flat... Then what 🤷♀️ you almost feel as lost as when you're phones gone 🤣
Yip been there, done it ! snapped cylinder head bolts, overtightened casing bolt resulting in a leak, snapped exhaust studs. I should have learned after the first one. Been using a torque wrench for years (probably around 30) I'm a foot/pounds man but newton/metres fine ! It's the same thing. I'm not sure if people still buy them but the Haynes workshop manuals used to have virtually every torque setting for a bike. Great vid ! cheers
Thanks dude. Oh my yes. The Haynes manuals. I think anyone over a certain age will have 100% had one of them haha
I had one for my Rover 200 💪🏼
Nice one, Vanessa 👍🏼 Have always used a torque wrench cuz I like to KNOW it's right. Safety and peace of mind are priceless.
YEAH exactly haha
Not everyone is mechanically gifted and knowledgeable, and everyone starts from somewhere hence any garage tips, videos and lessons, as this one, is a must watch and a great way to learn, as opposed to some previous comments below. So keep it up Vanessa, you're doing great!! Next ones? Bring on some oil and filter change or chain adjustments, that would be awesome too! Stay safe! 👍👍
Mega, thanks Nelio. Mega appreciate your support. It's lovely to see so many comments from others about how they've learned something. That makes me smile. Big thanks dude
One other important point Vanessa> If a ham handed user of a torque wrench does not stop at a "click" or "light" or that wrenches form of indicating the set torque limit has been reached. If they continue to pull on the torque wrench the torque will exceed the setting and still be applied.
It seems a popular subject on mc forums of stripped threads or twisted off bolts or heads. Cross threaded is also popular because people do not hand start the fastener. Also a big mistake is using ft/pounds in stead of inch/pounds ... reading the specifications and using the proper unit of force is necessary.
Gosh yeah good points. Maybe Darwinism will help some of those 😳😋🤪 hehe Sorry that was probably a little mean as they're very valid points and we all learn but I thought they were hopefully obvious 🤣🤞🏼
Complete agree !! It’s one of the most important tools I use in the garage to maintenance my Moto Guzzi, Ducati and Gas Gas trial. thanks Vanessa 👏👏👏
Nice collection of bikes dude! 💪🏼
I had to sent this to a guy who said I was being over exaggerating while using torque wrench on my cafe racer engine mounting bolt. 🥴🥴 May he accept the knowledge I'm sending to him.
oh gosh haha I hope it helps him learn... lol
That was a great presentation on torque wrenches. I have a couple of those same Teng torque wrenches, I keep mine safe in the plastic cases they come in and I'm always impressed by the build quality when I use them. I always use a torque wrench on my bike, everything is built to be as light as possible so it is very easy to over or under tighten a bolt or nut and cause damage or have something fail, which is the last thing I want when I'm riding.
awesome John, you have the same Teng torque love as me! We have our little red cases for when we leave the garage too! hehe got to keep them safe
Good video thanks. Thats an impressive collection. Continue to be impressed with the garage you guys have set up!
Thanks Simon. All change coming on the garage soon! Exciting times. Stay tuned hehe
thanks I need to learn how to use my teng tools torque wrench and found your channel to teach me. Now I know how to use it and have changed my transmission fluid successfully! :) thanks for making this video, you earned a subscriber!
aw yey, that's mega. So glad it was helpful, thanks so much for the sub Roller
Make sure the tire shop uses them when replacing or repairing your tires on your vehicle. Those air ratchets can over tighten the lug nuts and warp your brake rotors.
Very good point!! I've never thought of that 💪🏼
Very usefull tip I am gonna try to remember it when I need fresh tires 👍
Yup, and you'll never get the wheel off roadside when attending to a flat.
Love my torque wrenches. I seem to over tighten everything, I realised this when I cranked a titanium bolt down on my mountain bike headset. I rounded it off, managed to get a Dremel into cut the bolt, then there was an almighty crack as the head of bolt shot out just missing me and leaving a nice dent in the wall. 😳
Thank you for explaining in such simple terms. I want to learn how to maintain my motorcycle but it can feel completely overwhelming to me since I have no mechanical knowledge. Your videos give me the courage to go for it! Keep them coming please and thank you!!!
Aw that's lovely to hear. My pleasure. Keep at it and it will get easier for sure
Great guide on an under rated tool. Personally, a good mechanic/technician always uses a torque wrench, regardless of how many years experience they have. My epiphany of torque wrenches happened while on a training course at Cosford many years ago. Currently I've 3 in my armoury. Great tips on selection and use of the wrench's, glad to see you mention releasing the tension after use.
Mega, thanks Bob. I love how you call it your armory. Cosford mention too, RAF? Hubby is RAF
@@TheGirlOnABike Was RAF, now you'd find me on the Honda stand at the NEC ect.....
Oh cool!
If you use Newton-Meters on a Harley it will explode upon starting! 😀😀😂😂 seriously, great informative video.
Haha good point 🤣🤣🚜---💨
Incredibly important.
Went to a session with the Yamaha national service manager down here in 🇦🇺 years ago. Made the comment... How tight is tight enough (without TW), nearly always too tight. Then went on to espouse importance of TWs'. 👍
haha that's a great answer! Thanks for watching Graeme
Very informative video for the inexperienced person doing their own MC servicing.
Aw thanks!
Brilliant video, Very helpful and great advice.
thanks lovely, glad you enjoyed ❤️
This is a really good introduction to torque wrenches. I especially liked the caveats about batteries, anti-clockwise torque and releasing the tension after use. And even more thank you for being humble about the whole thing. I get a bit suspicious when I see a video where the person makes absolute claims about being right about everything.
Haha aw that is mega cool to hear, I am so glad you enjoyed it and it helped you. Thanks so much for watching yey!
Vanessa, nice review of the torque wrench and it’s uses. We use mechanical models and have several of them, both inch pounds and foot pounds. Most repairs should not be attempted without a torque wrench. Your In-House Garage Review is a great idea! Ride safe Vanessa!
Yey thanks dude! Mega appreciate the support on this idea. Less fun than riding but without maintenance there is no riding 😋
@@TheGirlOnABike .... your garage, tools, etc.... great idea during the crazy times. Thanks again!
Great talk on torque! You must be the Torque of the Town *groan*. But seriously though, Vanessa, nice production values and an inspirational back story to boot. Really hope your rehabilitation continues on the upward curve for 2021...all the best, Coops.
Thanks Steve. That was defo a dad joke haha but it did make me laugh! 😃 Thanks for the best wishes, here's to lots more physio and getting stronger [and hopefully less pain too]
Hi Vanessa how are you! This is a great video! I have been a bike tech most of my life and became a fully Registered Honda Tech in 1985! So many people do not understand the torque in metals and the elasticity in a bolt...the stretch point! The torque spec is where that bolt will hold its best before stretching or breaking if it does not break the bolt is still weakend and you are right not tight enough will come loose! If we are building a motor that turns 14,000rpm most of the time we better use a torque wrench! 🙂. Great job Vanessa!
thanks Donnie, so true
Great video. Torquing fasteners is controlled stretching of the bolt or stud. No stretch and it will come apart. Too much stretch and it damages the stud or bolt and different stretch will cause damage to the parts. If a “ mechanic” doesn’t use a torque wrench what else aren’t they doing. Run don’t walk away from them.
haha that's make me chuckle but I so agree! Run! haha 😃 Thanks dude
Went to school for and worked as a diesel mechanic. Yes, a torque wrench is a necessity if you want to do your own maintenance! Over tightening will warp all of those aluminum and plastic covers, leading to leaks and damaged parts. A persons safety is on the line when riding a motorcycle, so take the time to torque everything.
I 100% agree! Thanks Randy
Very nice. Different camera angles to break things up and also that out-door shot. Great work!
Yey, thanks dude! So glad you enjoyed, I'm slowly learning hehe
Great job again! I use a torque wrench on engine cases, axle nuts, and fork bolts. Other stuff like fenders and seats I just use the good and tight method.
Great vid, really useful. Nice trousers
Aw thanks Nick. I love the trousers hehe have them in a few colours now. By Revolution Race
Though I watch a lot of DIY videos, I don't have the guts to do anything on my bike. But, as you mentioned in the video aboutthe truck, while changing the car tyres, I always thought of whether its overnight or not tightened properly. I didn't know there is something like a torque wrench tool. This is a great information and an answer to my long term question. I'm wondering if there is a plier tool 🔧 like torque wrench which can be used as a one tool for multi use, as otherwise it would be so many of them. Informative and great video, thanks for sharing.
I'm so so happy to hear it helped and brought new knowledge to you. Yey. Oh gosh I've not heard of a 🔧 style. Maybe try Google. 🤞🏼
Brilliant presentation on such a controversial subject. Once you strip or snap a bolt you quick learn to gauge for the feel when tightening things, especially when aluminium is concerned. I’m glad you mentioned to release the spring after use, I used to get told off all the time as a young apprentice for not doing so 😂
haha thanks Joey. So true!
Nice video Vanessa , I’ve just bought a teng one! I am trying to get the torque specs for my old trials bike build!
On nice. Good choice. Thanks for watching
Nice torque, Vanessa. I love my torque wrench especially for those 6/8 mm bolts.
Yey thanks
My 1960 MGA "Maggie" had hammer-on "knock offs". Found my front wheel 1-1/2 blocks away.
oh wowza!!!
Vanessa! Been a while, and yes maam accent is still 🔥 take care miss 🙏🙏🙏
Hehe thanks 🇬🇧
Very well done , I've been an auto tech for most of my life I have always used a torque wrench to. Specs . Good advice !!😊
Yey!
As an “old fart” I can assure everyone that when carpal tunnel and arthritis sets in, those “ calibrated hands” don’t work worth squat any more 🤪. The torque wrench is your friend, and will save you many hours of aggravation, and money. Great tutorial by the way 😉👍.
haha love that!! So true, thanks dude
Very well explained. How many times have you rounded a nut, broke a bolt or something because someone has overtightened something instead of using a torque wrench. The cost of one is soon recouped as you don't have to spend on plasters and putting money in a swear box.
Yes yes yes. 100% agree ❤️
Funny story, I took a brand new bike for a long ride some years ago. All was fine until the front brake stopped working on first pull. More pulls, closer to expected result. Turned out the dealership had not done the pinch bolts on the front forks. Although they had been marked with yellow ink I have always since torqued every bike I have taken possesion of. New or not.
Oh wowza!!!
Thank you... have always been confused as to whether I need one or not. As I commented previously, new to biking (legally) and so starting to learn how to maintain my Honda CB125R...
My pleasure Mark. I hope it helped. I would say yes if you're doing maintenance, even if just changing tyres for the axle torque 🙏
@@TheGirlOnABike It was replacing the wheel after chain and sprocket set change that I realised how important they were.
It's a great tool to have and anyone who works on motors should have at least one, you don't need all the bells and whistles just a good quality brand. 👍👍 . I've been using them for years, and for the hard of hearing out there you can get a duel signaling wrench that has a visual aid to let you know when you have the right toque setting, in a pin that pops out or a light changers as you get closer. Cheers mate 😁
Thanks JC, Wow that's so cool about the hard of hearing version. What a great idea! Thanks for sharing the knowledge
I have a huge Teng socket set, hex keys screwdrivers etc all Teng!
and yes, always release the tension on your wrench when you are finished
If you always release the tension when finished, that will keep it working fine for years
Awesome. Well kitted!
Hi.I was told it’s important to release tension from torque wrench after use by unscrewing out .I didn’t know that
Yeah so true 🙏
Great vid.... Very informative and I'll be looking into a purchasing one for my bike once I've found out which one... Need to find the torque settings..
awesome! So glad it was helping dude, you'll wonder how you lived without it once you have one hehe 😃
You're a Teng girl, I'm a Teng guy and YES I do have an unusually large tool box.
Haha nice 🤣
Another great video from Girl On A Bike 👏
hehe thanks lovely lady xxx
I've spannered for over 30years and I'm a torque wrench fan.
Don't forget that lubricated threads require less torque than when dry, by upto as much as 50% less. So don't fully rely on waiting for that click if your threads have grease or oil on them.
Thank Nick. I'm not sure I follow or agree on the variation for grease as the manufacturers manual will always tell you if it needs loctight c oil, grease etc and thus have the torque value aligned to that direction. I guess maybe if you're made a mess and it's lubes by mistake 🤪 Great to hear you're a torque fan too ❤️
You are right, if you're following the manual by the letter, stick to the torque setting given. For me, I do like to grease my threads somethings, even if the manual says not to.
You repair your own bikes ! Is there a way that I can learn it ? At least changing clutch plates and usual ware and tear parts.
Yeah I do. Yes absolutely! I'm going to do a video on how to start out doing bike maintenance so that might help your mindset stay tuned!
@@TheGirlOnABike a
Awesome.
Nice! Good explanation.
I'll use a torque wrench when it's even a little critical.. Seen too many things that failed when experienced mechanics didn't use a tq wrench! (at work)
good point! Thank you, glad you enjoyed 😃
Great video, I would say torque wrenches are required with certain brands. I had a KTM 500 exc that would split the triple clamp if over tightened. Bolts had a 17NM limit on them. There's some scary videos of guys who've had thier whole front separate from the rest of the bike after a jump.
oh my goodness! That's no something i want to happen. Blimey, you're vulnerable enough on two wheels... yikes. Thanks for watching Dave 😃
So...happened upon your Vlogs whilst looking at AT’s. Figured....”Sweet, let’s suss out what the pom has on her channel about AF’s” - I pull up your Site and I must be a true bloke I guess.
First thing that catches my eye is “Torque Wrench” ( not wench - but wrench...*lol* ) and that was enough for me to subscribe. So I guess now that I’m here I will have to take a look around eh?
Pisser about getting your clock cleaned by the Cage driver. I use to road race and train 7 days a week; people just don’t see us sometimes - or - they just don’t care. Mate ended up in a coma for 5 months because he T-boned a car that did the exact same thing as your accident.
It may not have been on your bucket list, but instead, how about a badge of Honour - that you and the only “vehicle” ( your body ) that you have - worked through together and came out on top.
Be proud of your scars.
Cheers.
wow thanks dude. I had no idea where you where going with that comment haha. Made me smile, thanks for saying hi and for the sub! hehe 👍
Nice job. Aldi often have them in fairly frequently as a special buy. Worth the £20 or so. Think I got mine from Screwfix.
Nice, it's made how random Aldi is haha
I wish I could ride with you. I can get my trusty Honda XR600R out of the garage and so some enduro. And yes let you ride it and START it 😂😂😂. Keep it up well done and stay safe 😉
That would be cool!
Yes watching a babe trying to kickstart the XR 😉
Yes you are right and what a babe 😉
You are the three bees
Beautiful,blonde and a biker . Everything a man wish. Keep safe
@@alancamilleri aw thank you
Very informative video , on your bikes do you use 1/4 or 3/8 wrench the most ?
It really depends what bike I’m working on to be honest and what part. My gut feels like 3/8
I need them
Best!
Never bothered with them for years but now my bike is newer I wouldn't be without one 👍
nice I can understand that Steve
How can we use for angulat torque like 60°
If your talking The torque, specified with regard to the axis of rotation, is equal to the magnitude of the component of the force vector lying in the plane perpendicular to the axis, multiplied by the shortest distance between the axis and the direction of the force component then it's not pressure which u previously stated in your video also said is a torque wrench required that is bad advice on which you are trying to sell enough said just know your facts
Thanks for the points 👌it's all learning ❤️
Well done Vanessa so well explained. As they say it’s how you say it. I bought a jeep one time and one of the wheel nuts was glued on. I know that was bad. I see you have million dollar bogan music in the background.......anyway well done.👍
Oh my goodness. A proper cowboy must have done that! Haha glue. Golly. Oh is the music too loud? I thought I got it right 😫 I'm learning! Or trying to 🤣
@@TheGirlOnABike no the music was just right. 👌
Oh phew!!! 🥰
Interested in tung tools,been looking for a good supplier for years,help please!
i'd recommend looking online and finding someone local to you that supplies ❤️
Thanks for sharing some great tips and information, but why does the camera show the side of your face a lot of the time,, I find this very annoying
I am sorry you felt that way, but thank you for watching anyway and I hope you enjoyed it!
Good vid. 👌
yey thanks Charlie

Interesting. Have never owned one but, again, you've motivated me. Doubt I would have watched the whole video with some hairy arsed bloke telling me though. 😂 Well done!!
haha I can confirm my bottom is not hairy! haha thanks dude 😂
Phew! That's a relief!! 😂
I don't use a torque wrench. I tight them 1/8 turn before they break.
nice, I'm far less calibrated that you hehe 💛
@@TheGirlOnABike It takes 1000s of broken bolts to get the touch❗😜😄
Haha uh oh
You angel
