Shop Thread Gauge

Feels like quality in your hands. The only drawback, which I hadn't even thought of until after I purchased, is that you can't use this to check threaded holes that are part of an assembly. As a for instance, I thought I was missing a screw to one of my shop tools, which I later found. I could not have used this tool to find the size of a replacement screw unless I already had a screw of that specific size on hand to test in the gauge. Other than that, this works great!

This is an extremely well built tool. The design and finish are top notch. Its usability is elegant; beats dragging out a ruler or calipers. And it helps create a smarter shopping list for the hardware store.

I have used the screw guide twice. It has help me purchase screws & nuts with the correct thread type and size
