Metric & Imperial & US Screw Gauge SAE Whitworth 55 Degree & Metric 60 Degree & & US 60 Degree Thread Pitch Gauge for Industrial Measurement

good set physically smaller than I thought

Simple thread gauge. Works fine. Not expensive. Easy. The only potential problem might be losing it after use because of it’s tiny size when folded up. Not a terrible problem.

Almost 5*, but it skips over a few threads. (Eg it has 26G and 28G but not 27G)

Muy bueno

Very nice recommend

I saw "Metric & Imperial" and thought, ok, there will be normal freedom units. But I also saw Whitworth and thought, why not, can't hurt. But I think that the "Imperial" the description refers to is the Whitworth form - which if you think about it is a threadform that is not metric, i.e. it is _one of_ the "imperial" threadforms. That's what you get: metric and British Standard Whitworth.With that out of the way, I'm the perfect customer for this product because I already own a couple of perfectly functional thread gauges for normal American 60deg teeth per inch. I only lacked the metric part. And since I had normal American units covered, it seemed fine to add exotic antique British threads to my capabilities. I think that this Whitworth form (the first standardized threadform I believe) would be useful if you were an antique restorer/collector. Old bicycles, engines, machine tools, etc. had these threads. I think you could use this to check normal American hardware store bolts for threads per inch, but I would be cautious about holding it up to the light and trying to match the exact thread shape.The metric side, the reason I bought it, seems good. I even liked the fact that they stamped the German word for "metric" - if you live in the USA, using metric is like taking a foreign vacation to a nice place anyway.Some people complained about the visibility of the markings. My eyesight is normally not great for stuff like this yet I can see the markings with out my normal magnifier just fine. They are not weakly printed but appear to be durably stamped.I checked an M4, M5, and M6 coarse threads and they all seemed exactly correct. I can't attest that all of the values are good, but these are the most common three I'm concerned about.For the price, this tool is a bargain.

Great product, great price, great service
