EAWONGEENut and Bolt Thread Checker Detachable Nut and Bolt Size Gauge Thread Gauge Suitable for Detecting Fixed Bolts or Threaded Holes in Enclosed Areas

I can't tell you how many times in the past that I've picked up bolts or nuts from the hardware store only to find out that they are the wrong size. The instance that really got me to purchase this was when I purchased the bolts specified in my vehicle manual and they were the wrong size. I purchased this and used it to determine the proper size bolts.What I like about this set over the others is the adjustable cable clamp. I can loosen it up to put a lot of space between the size gauges or to take a gauge off the cable completely if I need it to get into a tight area. The gauges seem to be of decent quality and should last as long as you don't abuse them.

Nice to have around for checking thread sizes.

My dad has been wanting one of these for a while now and he loves it. I appreciate that it has two different colors to differentiate.

I bought this for my husband for Father’s Day. I constantly see him trying to figure out what socket or wrench he needs. He really liked it, he didn’t know there was such a gadget. He’s used it many times in the few weeks he’s had it.

Made of cheap material but they do the job. I should have purchased years ago.

Nicely displayed, works nicely for the needs I have witch is just identifying thread and pitch of various nuts and bolts.

Been looking for something like this for awhile. Works great

I tasted all the sizes, the tolerances were perfect. Must have in the shop

Should have bought this sooner. Very nice set and useful for finding the size and thread pitch. Having both metric and imperial together is very good. The size and thread pitch is easy to read as it is in white.

I’ve been guessing on sizes for years but this handy gadget takes the guesswork out of finding the right size and saves lots of time.

If you are like me and hold onto every nut and bolt that you come across….this item will save you time and trips to the hardware store. As a backyard mechanic, it come in very handy when I’m ordering bolts online.Highly recommended!

Works fine

the set covers most sizes you would normally be checking.
