Mitutoyo 188-151, Screw Pitch Gage, 4 - 42 TPI and 0.4 - 7mm, 51 Leaves, Inch/Metric Black

Was able to quickly confirm thread pitch on hardware from a late 50s drum. Gave excellent confidence before searching for expensive custom replacements for missing machine screws.

Definitely agree with other reviewers the seller should post a more accurate picture. This is the very finest, Mitutoyo quality, made in Japan - worth the extra money! Yes, you can buy cheap thread pitch gauges, but why would you? If you bothered enough to check the pitch, you bothered enough to do it with a great tool! Love the friction locking dials - they work very well!

It is as described

Very accurate

Very high quality.Gauges are smooth and nicely finished but,that is Mitutoyo. I expect it from them unlike the cheap Chinese gauges.

High quality tool. Brand name you can trust. I would buy this again, but I expect not to have to.

Expensive but you get what you pay for

Expensive but accurate

Some of the threads are ground flat instead of a point example 10 tpi , I wouldn’t have know but used it today and the gauge don’t even reach the bottom of threads compared it to my old starrett and there was a few of the medium course threads also like they ground the points off to much kinda odd from Mitutoyo but I guess it happens sending it back and will buy a new starrett gauge instead
