Nut & Bolt Thread Checker - 26 Male/Female Gauges - 14 Inch & 12 Metric for Quickly Checking Nuts and Bolts Inch or Metric and Verifying The Size

So after ordering wrong pitch bolts (a couple of times) for a motorbike build, decided to get a set of these. Do what they say and will save me more than they cost by guessing thread pitches wrongly, and wasting money!!! If like me you cannot tell a pitch or want to check a bolt size etc, these are a great addition to your tool kit.

This thread checker leaves you in no doubt about what size thread you need - width and whether it is metric or imperial. Just get your bolt and insert it into the nuts to see what size it is, and the same for checking nut sizes. Each nut & bolt is clearly marked - even on the chrome ones. The nuts & bolts come on a strong steel cable so they won't get lost.The downside is the cost. Wowsers! This must cost about a fiver to make but I paid £60 on Amazon, because I couldnt buy it anywhere else. The reason is that you can't make a mistake with this tool and it will last a lifetime, eventually paying for itself by stopping me from buying the wrong nuts / bolts that are simply labelled "M8" without the thread size.

Sizes would be easier to read if they were punched into the metal.

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.

Es una excelente herramienta para comprobar rosca de tuercas y tornillos métricos e imperial, pero es difícil de manipular porque viene todo en una sola tira de cable de acero. Yo los saque del cable y ahora los uso por separado de su cable original.

Heavy, sturdy and well made. All threads are clean and well cut. The size markings are clear and easy to read. I was kinda skeptical when I ordered it but figured it's returnable if it was of low quality. But I will not be returning it, this is a great addition to my shop tools! I can now identify thread pitch and size without getting my tap and die set out guessing with the thread pitch guage. Great value for the money!

Práctico si el tornillo a medir aún no está fijo en muro

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.
