I used this tool to figure out the size of metric screws I needed for a project. This tool worked perfectly and seems like I could use it a lifetime. It is very good quality. Definitely worth buying.

Really handy tool to have in the shop when you're trying to size stuff up instead of guessing back and forth from whatever you're trying to replace.

This is a very well made thread checker. All of the internal and external threads are perfectly formed, the text is durable and easy to read.My only complaint is it doesn't have M3 and 4-40.

Confirming thread and bolt/nut sizes is really helpful from time to time and this thread checker is very nice. Solidly built and well made. Would recommend if someone does a lot of DIY and needs to check for nut/bolt replacements, etc.

I always wanted a heavy duty thread checker for my garage, but I kept finding the ones made out of plastic, or the ones that are on a key chain and not very useful. This one is made out of metal, and will be mounted to my wall so that I never have to worry about finding it again.Everything is accurate, and exactly as I would expect it to be.
