This kit is very nice and convenient. I've used it multiple times since purchasing it as I am restoring a couple of Jeep CJs. Works well for bolts and nuts.Highly recommend.

Not gonna lie, I debated this purchase for YEARS!!! I've always simply whipped out the ol' tap & die set and played the thread matcher game to find the right size...it was meticulous and time intensive, but it worked. On a whim due to a deal of a price, i picked up this kit because it had the largest range of sizes i found; plus a box and color coded metric vs. SAE. Why did i wait so long!?! I love this kit...use it all the time and taught my wife how to use it too for her furniture refinishing projects. Just buy it and enjoy!

This design is great! You can easily remove each nut/bolt checker and carry them over to where your working to check size. I first considered ordering one of the checkers that are on on a board but it was hard to find a good place to hang it in my garage. This item if neatly packed in a small box that is easy to move around.

If you do a lot of repairing and put things together you know a lost screw or bolt without knowing the exact thread pitch can be frustrating. Not anymore with this kit. Absolutely 5 stars
