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

It’s a little pricey. Great quality. It will outlast you.

Expensive but you get what you pay for

The Screw Pitch Gage is nice, much better than the one that came in the Tap and Die Set. It could be much nicer if it was made from stainless steel so that it wouldnt have to be packed in stinky oil. I like that it has both SAE and Metric sizes.

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

Expensive but accurate

I’ve been working on a project truck for awhile now. Rust belt veteran. At least half of the bolts and screws are too rotten to reuse. At first, I would just eyeball them or try to find info online. Then, I graduated to a cheap version of this tool. I was still wasting lots of money on Grade 8 bolts that didn’t quite fit. This tool has already saved me money. It doesn’t seem like the kind of thing you’d want to spend $50 on but that’s only 10-20 bolts or a few trips back to the hardware store. It also makes working on the truck much, much less aggravating. Worth it.

As they say, it’s Mitutoyo. Nice quality and accuracy. The two locking screws are much easier to adjust so the thread gages are easier to position.

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.

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

Excelent product especially this version for mm or in threads, great surface finish, well protected by oil and a good box and plastic bag as package. Great tool . AAA+
