Wow! I can’t express how impressed I am with this Thread Checker. I’ve always wanted something like this to organize the random bolts and nuts I have laying around, and it exceeded my expectations. Right out of the box, I was struck by the weight and quality—this thing is solid, all-metal, and feels like it’s built to last a lifetime, which is rare for something I’ve bought from Amazon. The only minor issue I encountered was the slight stickiness on the back, probably due to the Loctite used for the male threaded pieces, but it’s not a big deal and cleaned up easily. Overall, this tool is definitely worth the money and has helped me immensely in organizing my garage.

I often need to replace a screw or bolt, or buy a matching nut, and this is a great way to see exactly what size I'm working with. (Certainly much better than my existing strategy, which is to take the screw or bolt to the hardware store, hold it next to various examples from the store bin, then make my best guess!)These is really sturdy and good looking, and has a LOT of threads and holes to match screws, bolts, or nuts. My one minor complaint is that the holes on the top to wall mount these are spaced a little weirdly to hit studs. I might have preferred one wider panel that I could mount across two studs, but it's not enough to take a star off, and I'll probably just use heavy duty command strips.
