Digging through a jar of loose hardware to find the right bolt wastes half your repair time. This nut and bolt thread checker lets you quickly identify confusing bolt and nut sizes so you can classify them and get back to the job — built for craftsmen, engineers, DIY enthusiasts, and hobbyists alike. The laser-etched markings sit under a protective anodized finish, so they won't fade or scratch off with regular shop use.
As a thread gauge it covers both metric and standard sizes: the 28-hole plate spans M4 x 0.7 to M14 x 2.0 metric and 6-32 coarse to 1/2-20 fine standard threads, while the 44-hole plate adds more coarse-to-fine standard sizes from 6-32 up to 1-12. It's a go no go gauge built to Go & No Go Class 2B ANSI standards for both internal and external threads, machined from anodized aluminum alloy 6061 and SUS304 stainless steel, so this bolt gauge holds up to daily workshop handling.
