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

Very accurate

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+

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

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.

I had never bought a Mitutoyo product before. Now Im impressed. The retail photo provided for this product is inaccurate by showing black plastic knobs instead of steel. Since I prefer steel, theres no complaint. The machining quality is great. Numbers are easy to read because theyre stamped into the steel, and not etched like lower quality tools usually are.

wish the numbers were bigger

Sure, you could buy a Chinese piece of junk but are the rest of your tools garbage too?

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.

I use this tool to measure threads on bolts for my mechanical work. It is a precision tool, easy to use and accurate.

Product completely as per specification, also delivered on time
