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

It is as described

Whats not to love? Mitutoyo is hard to beat, and it works for both SAE and Metric. I carry this in my tool kit to help identify fasteners when a quick visual doesnt always work, especially on custom hydraulic fittings.

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

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’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.

Spend the extra money to get a good one! I wasted a whole hour going back and forth trying to find out thread pitch on a bolt that ended up being 1.5. It was because my cheaper gauge was off! This is a quality gauge.

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+

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.

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