What our customers say

Anyone who has a workshop full of assorted and mixed nuts & bolts will find this gauge invaluable! Hung next to my workbench. Used often. A quick reference for all measurements. Thank you!

Larry

This makes it much easier to identify thread and bolt specs quickly and easily. You don't need to carry bolts or nuts to the hardware store, you can easily inspect and then replace them. Overall quality is good with clear markings and the gauges I used worked perfect.

Dustin

This is probably one of the highest quality nut and bolt sizers I have seen. The whole thing is made of aluminum with steel bolts. There is every size you would need for metric or standard in the smaller sizes and all of them are accurate.
