Inch Thread Checker

I love this thread checker, this one I can fit in my bag, and it has more sizes than most thread checkers.

I searched for three months for my old one. I had the other one for more than 10 years, perhaps 15. I couldn't live any longer without it. I bought another one. It is nearly identical. I feel like the stamping of the sizes might be a little smaller, but I am a little older. The eyes won't last forever. I guess that would be it, bigger numbers on the gauges.

Great product Convenient way to easily identify nut & bolt

Very nice set of thread checkers. Used to correctly identify weldnut thread size and pitch on a body panel. This wire mounted set made this possible as opposed to a wall mounted checker which assumes you are only testing loose nuts and bolts. Only improvement I could suggest would be to attach each piece in a way that allows them to rotate. I found twisting the thread checker piece resulted in an awkward twist of heavy springy cable. Got the job done, but had to try it three times because all the other thread checkers got in the way and were very cumbersome while trying to turn this one piece into the fixed in place weld nut. Surprisingly heavy, but much more durable than plastic gauges. Glad I bought both metric and SAE.

Provided EXACTLY what I needed to sort some bolts to put back in bins. Recommend this to anyone who needs to find out sizes.
