Nut and Bolt Thread Checker – High Speed Steel Thread Checker Standard and Metric – Complete SAE Male Female Gauge – Accurate Measurements

This product is well-made and very helpful, when sorting a bunch of small parts. The only issues I had with it is that 1) One of the pieces within the string of measuring devices had text etched that was off-center and nearing the edge (did not effect functionality, cosmetic only) and 2) There was an instance where I was able to mix a bolt which was standard and it fit into a metric slot. Not sure if that's the tool's fault or the hardware's fault, but it pretty much matched the threads 3 of the 4 times I tried it, but since I had others of the same type fit in the standard hole, i knew it had to be a false-positive result.I would worry that the cable would fray over time, but we can cross that bridge when we get to it.These measuring units are easy to use and slide easily along the twisted-wire cable theyre held onto. The laser etching is easy to read, and matches the reverse of the color theyre printed on (so if on white the text is black - If on black, the text is white.) The nice thing about these is that they dont JUST do bolts and screws... On the reverse of every measuring device is the matching NUT pattern to go with it.You can do bolts and nuts at the same time, to make sure they match up. You can also do stuff that has flared shielding on it, and stuff that has other hardware on it, like locking rings, as long as they dont get in the way of the threads. Be careful with Loctite. You can do it, but it binds up a bit, and will also get stuck inside if it's flaky.This truly is an all-in-one multi-purpose tool.

Works great and now when I go to the store I know exactly what I need.

This is handier than a shirt pocket. I’ve always had trouble finding bolts and nuts that match. This thing gives you thread pitch size of bolt or nut. Metric and standard

I like it but I wish you could take them off so i could spin them around easier. I ended up cutting the end off.

I have a rolling bolt bin and I hang this off the side. Makes quick work to identify nuts and bolts. It's good quality and worth the money. I'd buy it again for sure.

Good quality

Should of gotten the one with more but this works perfect for everyday household!

If only I bought this a long time ago.. I would have saved a LOT of time looking for a nut or bolt to match what I need..
