I’m seriously impressed with the Nut and Bolt Thread Checker (36 Pcs)! It’s one of those tools I didn’t realize I needed until I had it—and now I use it all the time. Whether I’m organizing loose hardware, working on home projects, or doing automotive repairs, this thread checker makes it quick and easy to identify the exact size and pitch of nuts and bolts.The layout is super functional, with both SAE and metric sizes clearly labeled and easy to read. Everything is well-organized on the wire loop, and the build quality feels solid—no flimsy parts or misaligned threads. I’ve found it to be extremely accurate, which saves me a ton of time guessing or trial-and-error fitting.If you work with fasteners even occasionally, this is a total game-changer. It’s compact, easy to use, and makes you feel way more organized and efficient. Highly recommended for DIYers, mechanics, and anyone who wants to take the guesswork out of hardware sizing!

I would definitely not recommend. I was sorting through bolts to find what I needed for a project. I could not find any 5 mm bolts although I new there were many in the bolt selection. Upon close examination I realized there was not a 5 mm gauge in the set. However I have two 8 mm gauges. Fit and finish is not great. Several of the gauges have sharp edges on the threads. I am outside my return window, so I am probably out of luck. Do yourself a favor and pick a different option.

These individually sized thread proofs are excellent for tight spaces and captured nuts and bolts

I’ve only had this thread checker kit for about a week. I’ve already found it extremely useful in determining a metric bolt size/thread pitch while doing some work on my wife’s vehicle, as well as the thread size/pitch on some ATV brake line fittings I was working on. Well worth the price, and very handy for any garage/shop/DIY mechanic. 5 stars!

There work great and fit in a nice package. I just spent quite a bit of time sorting my bits and bolts and couldn’t have done it without this tool. Only complain is that the foam that holds them in the case is already showing signs of stretching and wear after one day of use.Other than the foam, excellent value and great to have to help sort your nuts and bolts and also figure out what part you need (or have)

Some of the threads need to be worked in a bit, but other than that, it is a beautiful quality set.
