Does VEXTHYX’ thread checkers meet the Go & No-Go Class 2B ANSI standard.

Yes, our nut and bolt thread checker complies with the Go & No-Go Class 2B ANSI standard.

What features set the thread checker apart from similar products?

Our threaded checker covers most professional-grade thread and nut sizes, offering a one-stop solution for all your daily and work-related thread size identification needs.

I’m trying to decide between the plate-style thread checker and the boxed thread gauge set. Which one should I go for?

The plate-style thread checker is more ideal for daily or professional use. Simply match the bolt that you need to identify with the thread checker. If you need to inspect threads in tight spaces, we recommend choosing the boxed thread gauge set.
