6 Pieces Thread Pitch Gauges Measure Tool Set Stainless Steel Screw Thread Cutting Gauge, 3 Pieces Center Gage, 1 America Type, 1 Metric America Type, 1 Metric Imperial US for Industrial Measurement

I use mine at work regularly. Very useful and accurate measurements. I use them as part of my profession and don't need instructions. But they OUGHT to include them for people who don't know how to.

Nice Quality !

The metric set was good to go - easy to read, and fairly well cut. The standard set (SAE) was not so good to go, not so easy to read, and the cut on the metal degraded as the thread count went up. Likely will keep and try to use, but will likely not buy again.

They all match up fine with the respective threads I looked at.I like having the extra metric thread gauge, both are not the same though.One just has the Metric + Whitworth gauges, the other has the same but also includes some imperial threads with it (8, 10, 11, 14, 19, and 28 TPI)

For the price, I can't complain. But the online product description is poor and sometimes inaccurate. Moreover, the 52 and 58 piece gauges are mostly duplicative, and this is not made clear in the description, so it appears you are getting more gauges than you are actually receiving. And lastly, many of the finer pitch gauges are poorly stamped out and will be difficult to use for confirming screw pitches. I usually don't work with threads finer than 40 or 56 US TPI, and the gauges are mostly good to down to these sizes. For larger sizes, these are good to go.

Good set works great. no problems.

When a job is waiting and your tool supplier is low on stock and a four hour round trip away it’s nice to be able to rely on someone to send the tool fat while I get other work done.Nice tool, good range, fair price and best of all I didn’t have to soak it for days in evaporust because I saved a buck and waited a week bidding on a used ‘hope it works’ special.I recommend this for anyone pitching very small fine threading jobs.

This Stainless Steel Screw Thread Pitch Cutting Gauge Tool seems accurate enough for me; however, one of the triangular sets was very lightly stamped, so that the numbers are hard to read without getting it "just right" with the light.
