Gauge is all injection molded plastic so wear is to be expected against metal bolts. Used for most common US and Metric sizes Legends are positive projections from the tool surface with no shading which makes it hard to read. Bolt size functions use both holes and rods projected from the ends and work very nicely. Thread pitch indicators are very hard to measure, no instructions so it was assumed that the user must feel the fit of the bolt to the thread extrusion mounds. The markings for pitch are not clear as to which count goes with which mound. Having "thread standard" bolts handy allows the user to compare the known threads with an unknown sample. The edges where the threads are molded are likely to wear quickly as the user drags bolts over them to see if they "lock in" to select the pitch. The gauge is a clever idea that pretty much works and should have been easy to use.accurately.Read full review

This is exactly what I wanted and needed. Works great. Just as described and advertised. Fantastic price. Could not find the same quality at any lower price than I found here. I highly recommend this product.

I was really looking for a metal gauge that had threaded holes and studs, to distinguish NC from NF and their metric equivalents. This gauge is easy to use for nuts, but harder for machine screws, requiring matching thread samples. Even more complicated when you're working with a mix of US and metric sizes with similar diameters.

Very thick strong. Wish metric had more graduation to use as a ruler, but that is minor. Can size bolts quickly with this tool so far. Has some metric and standard sizes measurments but not all. Great quick accurate gauge.

After having a DIY shop athome I gathered many nuts, bolts & screws. This gauge allows me to properly ladle them easily and sort by size. Great additon.

Finally caved and got this universal tool to measure threaded bolts and nuts. Can’t believe the average price for the fancier ones. This does the job perfectly. Every tool box must have one.
