- The Wurth Time-Sert is a great way to repair stripped or damaged threads. This works much better than a heli-coil type insert as the time-sert inserts are solid, unlike heli-coils which are like a coiled spring. If you need to repair a stripped thread and you can’t drill it out and tap the hole to the next size up, the Time-sert is a great option. I managed to get my kit for about £90 from ebay- fave.co/2I6XwfB

I have used Cross Wire Inserts (Helicoils) for many years, I have only had a few wind out upon removal of bolt or stud. I just clean the thread out with the tap, and wind in a new Cross Wire Insert, job done. When repairing many stripped or damaged threads, the Cross Wire Inserts are far cheaper than other threaded bushes. Also if the stripped hole is very close to the material edge, the Cross Wire Insert requires a smaller new hole than an insert type such as these.
Thanks for showing us this kit. We never know when we need it. Spot on. And the explosion was interesting too 😃
You are welcome

A good alternative to the helicoil system, thanks for this! 👍
Absolutely, a couple of people have mentioned these recently, which has helped me out 👍
Thanks for the comment 👍
Fantastic product that should work all the time, every time.
I won't be in the market for this type of product but enjoyed the video nonetheless.
Thanks for taking the time to film and upload, thumbs up.
Thanks for the comment and the thumbs up 👍
Thanks for the information. This is a great channel.
You are welcome

@@ultimatehandyman What tap wrench is that ? Where can one buy it? Looks like one of those that will last for generations!
Great work! I have the Time Sert kit, and at the same time, I was looking for alternatives. I purchased the SENNMONN kit on Amazon, and it functions the same, saving me a lot of money. Looking forward to your video content updates.
👍
as always found this video very informative and useful
Thanks for the comment 👍
another great video simply the best on you tube
Thanks for the comment 👍
Thanks for making this as i was only aware of the helicoil type inserts. Much prefer those eclipse type forged tap wrenches too. Miles better than the cast aly ones that break if you drop them. Cheers.
Yeah, the American style tap wrenches are much better.
Thanks for the comment 👍
Thanks for sharing. It's very helpful.

GREAT VIDEO!
Thanks for the comment 👍
Informative video showing an effective solution and alternative to helicoils (which I don't trust in use by the way!!) Just a few things to point out here though.....The drill you showed wouldn't really be effective in a normal 3 jaw drill chuck unless you grip the shank of the drill - the reason it's square is so it's only to be used in the tap holder...… you're essentially using the drill as a reamer to obtain the correct sizing of the hole for the tap used...…..also a 'few turns of the tap wrench and a slight turn back to break the chip' isn't really the way unless you potentially want to snap the tap in the hole.... especially in harder materials like steel!! I recall from my apprentice workshop days reciting "1/2 a turn round, 1/4 turn back" which I still do to this day if I have to do any manual tapping of holes.... just a couple of pointers as everyday is a school day as they say... Thanks
Thanks for the comment 👍
my old boss told us never to use a drill with the drill bit in the time sert kit as they were designed to be used with a tap handle , he would have a fit if we used a drill .
Thanks to Eric for recommending time-serts. These can be expensive, but there are some bargains on eBay (make sure you shop around)- fave.co/3aO2vyr
I hope everyone has a great Sunday 😉
good for stripped spark plug hole too with the appropriate sized insert.
Thanks for the comment 👍
it`s always WURTH watching your channel, your the ultimate handyman...…………….
😂
I would advise using cutting oil when drilling and especially when tapping holes. Great vid
Thanks for the comment 👍
Oh damn, this is really useful! Luckily I have a Wurth shop not more than 1km away from me and I've already bought some of their stuff.
Their stuff looks to be top-quality German engineering 👍
Thanks for the comment 👍
I always had my problems with the helicoil system. I am using the Time-Sert since more than 15 years mostly on motobike engines. Since then the screw connections have been holding up again.
Thanks for the comment 👍
Much better but also 3 times the price of a decent coil type repair :) great vid as always!
Yeah, they are not the cheapest!
Thanks for the comment 👍
Well worth it if you are going to rely on it. I used them since the early 70s. Never had a failure.
When you said expensive i didn't realize it was that expensive, My god!
It is a quality piece of kit though ;-)
Thanks for the comment 👍
Never had a helicoil fail like that, BUT, that being said i buy the genuine stuff. I hear (grape vine) that outside of a few German made products and some French ones, everything else short of the original product is garbage. Lower quality steel, different geometries etc.
There is one thing i do, whenever the thread really needs to remain in place. It's not something everyone can do, but i have full confidence in the strength of the repair, and that is, i spot weld the last coil section into the original metal. Obviously, this doesn't work for dissimilar metals, and you need to have a copper thread plug to maintain the hole, but it works exceptionally well to keep them in. On my brother's farm, i've done this to every farm tool that lost threads, we both had equal thoughts about losing threads or actually seeing them come out like in your intro, like a spring, so we decided to go the extra mile.
I think the toughest test is the bar that keeps his steps upright, in season, that sees a lot of use and whilst it would not lead to any catastrophic failures if it did break, it hasn't so far despite being removed with regularity to reach the battery well.
I looked for genuine Heli-coils yesterday but could not find them, I could only find V-coils (we use these on site). There does seem to be a lot of cheap makes out there, which I would definitely avoid!
Thanks for the comment 👍
if you look closely at the last two threads on the insert they are not formed the same as the rest of the insert. when you use the driver it cold rolls the last two threads which then locks the insert int to the work piece . the driver ideally needs to be able to exit the end of the insert to lock it into the workpiece tightly ,
they are a great repair item and in my opinion better than helicoils .
i used to use them a lot in a previous job. .
spark plug inserts where a daily occurrence as were inserts for sump plugs in ali sump.
Thanks for the info, Paul 👍
@@ultimatehandyman no problem. They are great for repairs to stripped threads.
Paul, you are correct...this applies to blind holes using the longest insert for the most thread grip. We purchased a second expander tap and ground the tip; then used it to follow up the first expander to get the last bit of grip.
You should have a look at Kennsert as well
£90 per kit.. Blimey!
Yeah and that was the cheapest one I could find, some M6 kits were £130!
Thanks for the comment 👍
This got my sub and upvote
Brilliant, thanks 👍
Handy to know there's an alternative to the Helicoil type. Not cheap, but then what price is a replacement part?
Another great video. Shows the method of use clearly and concisely.
Thanks for the comment, Dave 👍
Not all helicoils are made equal. Many off brand units that are frequently interchanged and don't work well. That said the Wurth units are the best for hard threads in soft material. I have used them into aluminum on vibrating tables running at up to 20hz and when they do come out can be replaced with a new insert and locktite with little problem. However they don't like heat compared to a Helicoil.
Thanks for the comment 👍
Great video, thanks for making it. But what I don't understand... the drill bit is larger than 6mm, isn't it? Must be since the TimeSert-insert's OD must be larger than 6mm. So how come the drill bit fits into the hole with the stripped thread? That hole must be ~6mm. Is the drill bit tapered? Asking because whenever I've done helicoils, getting the initial drilling straight (perpendicular) is the hardest part because the drill bit rocks around on the surface - it doesn't get any guidance from the hole because it's not in the hole (yet). Thanks.
Helicoil is the original brand that manufactured them and still do. Lots of other companies make them now but calling them helicoils is not quite true they are thread inserts.
That is correct, I thought I said "helicoil type inserts", I blame it on my medicines 😂
Thanks for the comment 👍
I have to disagree with you.
I have used helicoil for past 40 years 100's if not 1000's of times and Time sert occasionally.
I have never ever had a helicoil come out but I have had at least 8 timeserts , fitted to spark plug threads (not by me) that have wound out on the plug seat.
As in all things, preparation is everything
I would always use a genuine helicoil over any other thread repair system
I think we use V-coil on site, they tend to come out regularly, but we don't use time-serts, so I can't compare. I imagine that if they were threadlocked in (for the job that I do they would be better).
Thanks for the comment
Same boat, I've repaired 100's of damaged holes with helicoils and never had any issues, I've used the locking type of timesert where you have to hammer the locking pins in but only on spark plugs as they will be removed numerous times.
Only downside to the helicoils is that they need a decent amount of material to screw into, whereas the timesert can be fitted to thin and shallow material and can in many cases add some reinforcement to the item.
It's always good to have a choice of repair options depending on the application.

Hi there, could I use a helicoil in a glow plug if I need to as I have a snapped and seized glow plug and plan to remove it this summer when the weather is warmer to heat the engine to help try keep the heat in it.
Any advice would be appreciated.
Me too then I guess, as others have raised the point.
Helicoil have always been the 'go to' system in my service department since the 1970's and now that I'm retired I have a few kits in my work shop too.
By the way I deal with the Wurth rep. each time he comes around,...great products they have too.
@@tecfixed2840 I agree, Helicoils are fine so long as they are correctly installed, with the correct size hole, tapped correctly and square to the surface, and fitted with the correct tool. The inserts with the locking pins are called Keenserts, apart from the locking pins their other advantage is that they use a standard tap, not a special Helicoil or whatever.
@1:50 - "they are slightly more expensive"
@ 2:38 - "the kit is a lot more expensive"
Can't wait to see how much they cost by the end of the video
🤔
Good demo, gloves look like a hindrance
I'm used to wearing them 👍
Great thanks, I've luckily been able to find a 2nd hand kit to repair my sparkplug hole. Just wondering, would you use red loctite to keep the insert in place permanently?
Not sure about that, I don't think Loctite is necessary with Time-Serts 🤔
Thanks for the comment 👍
No, red loctite releases with heat.
Nothing wrong with Helicoils if installed correctly, I've been using them professionally for years. By the way, "Recoil" is a cheap copy of Helicoil and still fine if installed correctly
Just f@#$ed up the helicoil repair, I wish I had gone with the threaded bushing kit since the beginning
😱
Looks great. Why is it though you couldn't just re-tap the hole, rather than having to fit the insert?
The hole was stripped, so you would have to re-tap it to the next size up (M8), but this is not always possible because you might not get the M8 bolt through the part that bolts to this part etc.
Thanks for the comment 👍

Just viewed this video - thanks for sharing My concern was when you said that the aluminum block was a hydraulic fitting and then began to wipe and blow the metal chips all over the place. A chip / shaving could get into one of the passages and really cause issues, even dislodging and entering the pump and ruining it
Personally, I would cover the passages / holes with masking tape to protect from havoc.
Good morning to you Sir, another rather good video and expertly explained. For my own peace of mind I'd also use an alignment tool as I'm an expert at tapping gone awry, I've seen these being used and it might help me and any others with an engineering disability (unable to tap a straight hole). Ebay: RDGTOOLS SELF ALIGNING TAP WRENCH REAMER WRENCH
I do find however that starting a tap in the pillar drill first (by hand) then releasing the chuck and finishing by hand is a much safer method (given that there is no flex in the pillar drill table). I'm waffling aren't I? Anyway carry on Sir :)
I'm going to order one of those, I have often thought about making something similar, but now I don't have to - fave.co/2IsRGFF

If the original hole was say an m10 when repairing the thread do these or helicoils then change that hole to a larger bolt so an m10 will not fit anymore ?
No, if the original hole is M10 and you get the M10 Time-serts the new hole will also be M10
Thanks for the comment
what brand tap wrench are you using? It looks good quality
I think I bought it from RDG tools on eBay- fave.co/3cKnwvm
Thanks for the comment 👍
Have a question a little bit of help I have a 2003 CL500 Mercedes my hydraulic power steering pump threads are stripped T12 metric bolts can someone tell me the correct kit I need
It's probably best to ask a mechanic, to ensure you get the correct kit.
Some motor factors will know which kit you will need 👍
hi, the thing that is stuck in my mind is this: my motorcycle's crankcase plug slot was licked and its size is m14x1.5. I want to put m14x1.5 size plug again. I want to get and do time-sert for this, but what measure should I take? What should be written on the time-sertbox?
You just get a M14X1.5 kit, example here- eshop.wurth.co.uk/Product-categories/Thrd-repair-oil-drn-plug-thrd-M14-x-1.5-Time-Sert/31086006011402.cyid/3108.cgid/en/GB/GBP/
@@ultimatehandyman thank you bro
I use a helicoil and timecert just to make sure.
🤔
A properly installed helicoil will not " back out "
They come out regularly on site, when you remove the bolt!
Thanks for the comment 👍
Helicoils are mostly junk! We switched over to Timeserts in the late 70s; never looked back.
That's a lot of box!
Yeah, you could put your sandwiches in it too 😂
Thanks for the comment 👍
Yes, no doubt they are a good system but I'd have to politely suggest that they may be as good as Helicoil,..I'm just not sure that these Worth Time -Serts are better!
They might not be, but I've had a few Heli-coil type inserts that have unscrewed with the bolt.
Thanks for the comment 👍
@@ultimatehandyman That's fine,..but you know what I'm going to do,..when next I see the Rep. from Wurth, I am going to inquire after these Time-Serts and see if I can get a set from them.
Then I can give them a fair test on a little project I'm doing now, and see what transpires. Could be that they ( the Time-Serts ) will work better,..we'll see.
This is a PS,....it looks like there are some 'off-shore' knock offs out there,...I just noticed a set on Amazon.cam,....sure looks like a 'cheaper' copy to me!
Buyer beware!
How to choose the size?
You get the size closest to the size of the original bolt.
Thanks for the comment
Timeserts are overkill for most jobs. Considering you can buy numerous helicoils for the price of a timesert it often doesn't make sense to invest that money except in frequent use or high criticality fasteners.
All very well when it's the company paying, I'll just use a helicoil and redo it if it unwinds on my own stuff.
Thanks for the comment 👍
I think I found it. Is it RDG?
Yes, it is.
You might have asked this question as I vaguely remember trying to find a link to it on ebay- then I could not find the comment to answer it! (TH-cam comments is causing me lots of problems)
Thanks for the comment 👍
Dose this keep the hole the same size or make it bigger?..
It keeps the threaded hole the same size, so if you use the M6 kit, the finished hole will be suitable for a M6 bolt.
Thanks for the comment 👍
@@ultimatehandyman what about from the original size before the kit is used?. Thanks for the reply
It needs drilling out slightly larger, so that the hole can be tapped for the insert 😉
Please identify your tap wrench. Is it Starrett?
Its RDG, they sell them on ebay (UK)
Thanks for the comment 👍
That huge kit box and it's almost empty. Not wurth the money in my opinion 😀
Ha Ha, very good 😂
It then gives you a place to keep the various lengths inserts....all TOGETHER with the kit. Original ones came in a little green box with little extra room for the inserts. Besides, Wurth had boxes they needed to move. LOL
Really fail to see how this is any better than a standard helicoil. Surely the time sert insert is just as prone to backing out when removing the fastener as the helicoili insert?
Only advantage I can see is that this system doesn’t have the tang which can be a bugger to remove in a blind hole.
I think these will be easier to thread lock in position, as they are solid- unlike the helicoil type inserts, which are more like a spring. Also they have a seat on the top of them, which should make them easier to use time and time again. One problem on site is that when I undo bolts that are in Helicoils, the helicoil comes out with the bolt.
Thanks for the comment 👍
@@ultimatehandyman i suspect it depends on the bolt sizing. iv used helicoils from M10 down to M3 and using red loctite have never had them back out
You scared the bejesus out of my when your logo went off in the middle of the demo. I thought the thing had gone deadly wrong and your daks had been set on fire. Yikes! 😬🔥
Ha Ha, sorry about that. I even reduced the volume for that part, as it is quite loud when the volume is not reduced!
Thanks for the comment 👍
Is this really “Wurth” the money? 🤪
😂
Made me laugh.
If you install Helicoils correctly they don’t come out. There is no problem with Helicoils if fitted correctly. They don’t come out and you don’t use thread lock. Helicoils were invented as a solution in manufacturing and assembly of parts in the aviation industry to secure parts together as threading directly into alloy is a poor engineering solution. They are a proprietary fixing device that also work as a repair device. Time Certs operate in a different way. The downside to time is they require a larger hole to be drilled out. For some applications there is not enough material for Time Certs. People like Time Certs because psychologically they feel better as they look like a more professional fix, but this is not the case.
First
I'm glad you are not a referee at the Olympics 😂
Thanks for the comment 👍
the downside of aluminium, nice kit though , heard about wurth never looked into the brand, not a brand i see here in Au, still no match for your how to remove broken bolts video, LOL
I think Wurth are big in Germany, they are an expensive brand- but probably good quality.
That broken bolt video has had plenty of views 👍
