Boltsize-It Gauge, Blue

Saw this on tools you need on you tube and it is a very function tool to add to your tool chest.

Like others noted, this came with a large sticker on the back that was difficult to remove. Other than that issue, the product is great.

none

Without careless use it gives the impression itll last.

Accurate, simple tool. A must for any tool box.

heavy gauge plastic, would highly recommend

Needing to find out the size of a bolt, we got this and now Im not sure how we did without it. There are a surprising number of opportunities to replace lost hardware and this little device has an amazing number of options for figuring out bolt and nut sizes. Not expensive and worth every penny!

I got one of these years ago as a freebie with a subscription--still have it and use it often. I am, however, splitting my workshops--the wood shop will stay down and the metal will go to the garage. This means splitting out some hardware and tools I decided to to get this improved model for the metal shop as I still get new and used hardware in bulk and need to identify it. Also, this is helpful when you need to size a replacement for a broken screw or bolt. You can measure lengths in SAE and MM as well as a pitch guide for threads. Coarse and fine nut/washer posts too. I like this one and it is already on my toolbox in the garage on a magnetic hook. Also from Amazon, I have a second sorting and counting tray that makes putting the loose items back in the container easy. The two together make most hardware jobs much simpler and I recommend both.

Its a really useful durable chunk of plastic for a home mechanic. Only minor complaint would be to determine if thread is fine or coarse on a bolt, you need to count the threads. If you have the companion nut, you can simply see if it fits over the shoulders on the posts. Most of the time coarse and standard threads are easily distinguishable though, and I cant think of a way they could have incorporated a quick way to check into the design other than having an additional set of threaded holes which would likely wear out eventually.

Nice quick resource - takes up no room in the tool box!
