Excellent item for the mechanic
Our nut & bolt thread checker is specially designed to verify the size of nuts and bolts in either inch or metric in an accurate, easier and faster way, especially suitable for mechanics, allowing them to quickly identify nut bolt size. It will be a good tool, it takes a few second for nut and bolt size check.
1. A rigid PVC plastic box storage ca
Our nut & se keeps each thread checker organized.
2. Three ways to read the size: each thread pitch gauge in this screw size and thread gauge tool box is engraved with the corresponding size, with the corresponding gauge size sticke inside the box and the EVA foam holder with the size of each gauge printed on it.
3. The bolt and nut thread checker/bolt identifier set makes it easy to check a fixing bolt or threaded hole by simply taking out the individual gauges, so you no longer have to rotate the whole thread checker on a wire.

Product came quickly. Sure enough, it was barely a few weeks and I already had to use it! Got a replacement bolt for my wife’s Honda in just seconds! Lots of useful sizes standard and metric!

Lots of common male and female thread devices in the kit which has well-marked slots for receiving their respective thread gauges. Needed this for figuring out what bolts and screws to used for furniture after moving to a new house. Good price. Easy to use. Expansive set of gauges.

I liked the idea of size checking bolts prior to removal and also checking bolts at the store in case they are mislabled in the bin. The size checker fits into your pocket.

One of the biggest mysteries of my garage screw/bolt/nut collection is that I never know exactly what I have and what I need. I've never had a thread and bolt size checker. This is perfect. The pieces are removable, so you can check your bold or nut size on your project rather than having to remove them. This works particularly well when you are looking for a nut for a hard-to-reach bolt. This lets you quickly size the bolt in the hard-to-reach spot, and then you can turn around and size the correct nut for the bolt. Brilliant!The kit comes in a nice case with everything clearly labeled. It includes metric and imperial sizes. I am actually looking forward to organizing my nuts and bolts this winter.
