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

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

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?

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

Bom

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.

Expensive but you get what you pay for

It is as described

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.

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.
