Acme & Trapezoidal thread pitch gauges

[scottmk1]

As per the title, do these exist? And if so where can I purchase such items?

You can generally find Acme thread gauges on eBay, there is one at the moment for £70 used not cheap , the metric versions are £££££££££££, unless you are very lucky and find a used one

Though if it's just to check your getting the right number of threads, the normal metric and imperial gauges will give you a good idea of the spacing

Cheers, didn't realise they were so expensive! I've been using normal metric & imperial gauges to measure the pitch, just thought I'd maybe get the proper ones for the job, but not at that prices.

Won't a ruler do to measure the pitch?

Maybe he should offer some for sale on here.
