🔩 Essential Marine Bolt Supply Nut, Bolt & Screw Gauge in Standard & Metric Coarse & Fine Measurements for Diameter, Length & Thread Pitch (Red) Review

This is an inexpensive gauge but it gets the job done and provides both SAE and metric which is a good cost saver for the occasional do-it-yourselfer. It's plastic and has filament sensors on the back, but doesn't support threading like the metal. I knew that although for me it was a good buy that suits my needs.

This is a completely different design to most thread gauges. The posts on the sides are designed for measuring nuts (both small and large), but they're smooth on the outside. Others I've seen require you to thread the nut onto the post, which is no good if your nut has damaged threads. The thread profiles along the front of the card allow you to customize threads on almost anything. I've never seen this method before, but it seems pretty nice and accurate.

This is a very durable and beautifully designed pressure gauge that is convenient to carry around the shop. It has both SAE and metric calibration. The red color makes it easier to find when searching. The only thing I don't like about it is the thread gauges as they are just protrusions on the back of the device you screw to. Threaded holes would be better, but with an injection molded plastic device, threaded holes aren't very practical.
