Here is a quick video on zeroing a micrometer. The same process applies whether it is a metric or a standard micrometer. This micrometer has .0001" increments as opposed to .001", so it has the vernier scale as well. Pretty easy still, but keep in mind that you need to line up the 0 on the vernier scale as well. The micrometer that I am using is from the Anytime tools kit available on amazon: Anytime Tools Professional Machinist Inspection Tool Set: DIAL CALIPER / MICROMETER / Stainless Steel Ruler - วิทยาศาสตร์และเทคโนโลยี

Got a very old mic from an old engineer and the barrel wouldn't move. The video confirmed that that's definitely how it's done, so this gave me confidence to increase the "persuasion". With the barrel clamped in the 4-jaw and a mallet, I got it to shift. After a few times ging back and forth it can now be adjusted normally. An old tool saved from the bin. Thank you!
Helpful video, thank you. In addition, to zero a mic that is extremely far out of spec and putting the thimble zero in a poorly visible spot (over the top or around the other side) , the spanner wrench has a small side, which is used on the ratchet stop keyway to loosen the ratchet (which your mic in the video has), then pop the thimble back toward the ratchet, and bring the thimble zero to your preferred orientation before reassembling/resnugging the ratchet. Again this is for extreme cases, but it covers ALL adjustment with the addition to your video. Good share sir!
Nifty video and exactly what I needed to confirm how this is done. Thanks for taking the time to post the video, guys like you make my life just a little easier.
Thank you for your patient demonstration ❤
You are welcome!
Such a simple thing and it's been driving me nuts how to figure this out - plus I wondered what the spanner thing was for. Thanks.

This was exactly what I needed. I watched several other videos and none of them showed how to adjust my micrometer set as they were showing for a different style of adjustment. This will work for VEVOR branded micrometers like mine. Very much appreciated!
Something to keep in mind is that the standard gauges in some of these cheap micrometer sets are not exactly to size. Mine are all 0.0008-0.0020 off of true size making the micrometer very hard to adjust to true size.
thanks! just bought polish mics for a jdm honda motor rebuild and gonna get it done thanks to this vid!
Awesome! That will be quite a project.
Thank you for the Video, I just ordered the same Micrometer (or at least it looks identical) I’m trying to study up on Using one. Dial Calipers are all i have ever used
Very informative video. My micrometers came with zero instructions. I couldn't figure out what the little wrench was for, I couldn't figure out how to zero the micrometer. So thank you, thank you, thank you!
No doubt it can be discouraging to have under 50 "likes" when you took your valuable time to make a video, but this was quite valuable to me and I'm adding it to my Reference folder. Today my first micrometer arrived - something I've wanted for a very long time (50 years!) - and it's a Fowler that almost looks the same as what you used here. It took me a minute to realize that mine is the cheaper version that goes to 1/1000th of an inch, while the one you demonstrated goes to 1/10,000th (i.e. why can't I find those last numbers he has?). Good learning experience. Thank you!
Some have a tenth reader, some don't.
My micrometer is good quality, but when I opened the case, no instruction manual! Thanks ever so much for helping me get the thing calibrated.
I thought that I knew how to zero a micrometer WRONG ! Didn't know about setting the micro adjustment . Thank you very much
Liked and subscribed. I thank you for the quick refresher.
Thanks a lot. My new mitutoyo was slightly off right out of the box and the barrel wouldn't turn easily. So I thought I'd check out if this is actually how it's supposed to be done!
Gracie mille!
All theses years I always wondered what that bar was for lol. Now I know thank-you great video
Cracking down on small channels. 3 years ago. That is definitely when it started.
Thank you. Very cool. I like it. I needed to see it. I've just zeroed my micrometer.
Very well explained. Point to point.
Very helpful, thanks for the video!
thank you for this and the link to spanner
Nice video, but I like to make one remark. Before you start calibrate you have to clean both or all contact surfaces with a piece of shammy leather. Even when you have a set of precision gage blocks it’s necessary to clean everything perfectly before calibration and when it’s possible take care aboutthe temperature.
Awesome, thanks for sharing this.
Good video for zero adjustment i like it. THANKS.
Thanks brother.
Many thanks, this video was really helpful. .....I have noticed the same small hole on the right side between the ratchet and the thimble. The other side of that little spanner perfectly fits in. What is it for?
Man that was pretty helpful,
Thankyou 😊
Excellent vid. Thanks legend!
Thank you, you help me a lot
Super helpful, thank you
Thanks for the guide
Big help, cheers.
Just got one and was scared of using more force to turn the sleeve .. but this was just what was needed.
Not to be a troll, and I only just learned this myself, but Mitutoyo suggests turning the ratchet 1-1/2 to 2 full turns to exert constant measuring force. Until I read this in the insert with my new micrometer today, I had always done it like you do in this video - just a few clicks.
Not trying to negate your effort for such good video but questions I have. There is another hole on the nimble end and the spanner wrench has a smaller hook at the another end. Is that meant for making other adjustment of some sort? If so, what? Torque of the clicking?
Thanks for the help. Trade school student trying to learn and fix a micrometer given to me
Good luck. I was a CNC Machinist for 40 years.
Good job👍🔨⚒🔧👍
That looks like an Etalon? I just bought a 0-6" set. Pretty penny but the very best. Thanks for this flick. Bought me a spanner too! :)
He's using a cheap Chinese mic.
Great, thanks! My Draper turned up without any instructions!
Worked for me
Bam subscribed. Hope it helps fill the small gap to your needed goal to sustain. Just dont start putting up 10 min videos that should be 5 mins max with 5 or 6 ads if you get monetized.
I have some issue but the lines instead of matching getting 0.50 error I can't figure how to solve this issue.
Thanks for the how-to. Just got my first micrometer and I need to zero it.
@Chris Cox. I have 11 micrometers, welcome. A couple of quick things, never store the closed in the box. Allow room for expansion and contraction. Allow the micrometer to acclimate to changes in temperatures if stored cold but using in a warm area. Many, like his, has phenolic pads attached to the body, keep the heat from you fingers from changing your reading. Just thinking out loud.

Nice brother
Thanks man!
No problem!
Helpfull vid
Great video! I am just wondering, how is TH-cam cracking down on the small start up little channels?
Thanks! They aren't doing us any favors, that is for sure! The new policy is that you need to have 1000 subscribers and 4000 watch hours in the last year to monetize your channel. Luckily I finally hit 1000 on this channel, but it was tough because I try not to be too pushy about getting subs and this channel is more of a one stop for a lot of people rather than a repeat like a niche hobby. I have another channel called "The Home Winemaking Channel" which gets roughly the same view count but way more subscribers since it is a much more focused topic.
What do we do if it's so tight it won't budge?
THANKS MAN!
No problem!
thank u شكراً
Thank you ! Is it that popular Chinese model from Ebay ?
It is from the "Anytime Tools" machinist set. I got it off Amazon and it included a set of calipers also
@@TheHomeWinemakingChannel Thank you !
Hi there can you tell me what size and name of tool I need?
You will need a small spanner wrench. If you search spanner for calibrating micrometer you will find them. You might have one hiding in the box that your mic came in also.
this micrometer good
Ive used then for 25yrs and never used that wrench. No more math in my head lol
lnS , i did it for the algo so they can take can take a bill do it .... yea
Damn, I bought an old NSK one on the fleamarket for 10EUR and I don't have the wrench. It will be probably more expensive than the micrometer...
I thought one needed to use shims.
You don't want the nine to line up.
You want the zero to line up, otherwise you're off by 1/10,000th.
I came here to say this same thing.
@@ryancameron1610 At least he said zero, not calibrate.
Urdu launched pleas
Well if I sit through this 2.5 minute add, hopefully you will get something out of it .
I mean it's even visible on the camera that it is still not lined up properly. But thanks for the tutorial.
I add my Thank to your many others.
