2 Pack Thread Pitch Gauge Screw Pitch Cutting Gauge Caliper Gages Measuring Tool, 51 Pcs America SAE Type and 58 Pcs Metric&America SAE Type&British Whitworth

Yes, this is a way to gauge pretty much every thread size/style in use. But that's part of the problem - the markings on the many, many gauges involved are sometimes hard to read or aren't meaningful, because they aren't marked with units. So, mostly useful to apply to a fastener, and then apply to what you think should be a match to if, indeed, it's a match. Not very helpful if you're trying to measure a bolt, expecting to be able to read the gauge and order up what you need.

After a month of use there is nothing terribly wrong with this item.However, I do feel that over time these gauges will not last. As seen in the stock photos, the gauges fan nicely and have more than enough teeth to measure the pitch of a bolt, but the axles are tightened by plastic knurls and mine have already “stretched” and won’t tighten further, making for loose fans that open up in transit. The markings for pitch size are only printed on, not stamped or etched, and will wear off with time.For myself I would not have said there were 51 “pcs” and 58 “pcs” , to my thinking there are only 2 pcs each with many gauges inside. if the gauges were allen keys or torx keys in a set, they would be listed as only 2 pcs… but that is just a personal gripe against the current style of “puffery” in listings/advertisement.If you are a diy-er or light user these will work fine. if you are more than that, I would recommend looking for a higher end item with more long term durability.

Needed metric 10x1 thread. Not in this set

It should work for what I need.

great price and product

Great , buy, fast shipping, Quality product, ThanksRaymond D.

They're not accurate and a little difficult to read, made cheaply of cheap materials.

Great tool to have where my dad has old SAE but i have differently type lol, so. I get all these when need.

Por el precio es un buen juego de gauges. Me gusta que tiene gauges para roscas métricas, withworth y americana a 60 grados.

Es una herramienta de gran calidad y muy útil para revisar los pasos de roscas
