A must for every shop and hobbyist.
I am not sure why I didn't buy one of these many years ago, my shop guys use this daily. It has really cut out missed identified threads.

Does the job for good price. Recommended
I liked these ok. Everything you need here. On chain won't lose them. The "bad" is the threading isn't the best I've ever seen, some rough. But usable. The "good" all on a chain so don't lose them & all in one place for all sizes A few burrs but easily fixed. I recommend this product. They work great. At good price. The metal is dry so a little. Vasaline or light oil on the ones u use makes it easy to use. I'd buy again & recommend good price

It works both on metric and SAE bolts and metric over a wide range of sizes.
Arrived in one day just in time to successfully use it to determine the size and thread pitch to get my equipment back in service.

A Much Needed Tool
Every home and garage should have one of these! If you tinker in your garage or are a do-it-yourself type of person that does not believe in tossing everything to the landfill this is great! Never worry about purchasing the correct nut or bolt again, no need to remove a nut or bolt from your project to match up at the hardware store. If time is a short or you cannot get out and you need to order your replacement / project nuts and bolts you now know the correct size with no guessing! The quality is good, they function great. Threads are accurate and clean. A true value over the plate style and a money time saver! Definitely 5 stars, if 10 could be given I would give it 11!

Should have bought this first
Bought it after we got the size of a bolt wrong 5 times. Feels sturdy, sizing is clear, lightweight. Glad I will be ble to check the other wing nuts I bought... I had been buying them in the wrong system.

Wouldn’t buy again
For me, it’s not very user friendly. I’ll just stick to my old thread guage. Cumbersome…nothing wrong with quality or workmanship
