The Inch Thread Checker is an accurate and easy-to-use thread identifier for both nuts and bolts.
Each individual gauge
features a male threaded stud on one end and a female threaded hole on the other. The Thread Checker
is especially well suited for distinguishing between similar inch and metric threads.
Conveniently assembled onto a wire loop, it's the perfect portable solution! Hang it on your shop wall or store it in your tool box for safe keeping.
The Thread Checker, also known as a Thread Identifier or Thread Verifier is a great addition for any Home, Hobby, or Inventor's Work Shop; Auto, Motorcycle, Marine, ATV or RV Repair Shop; Heavy Equipment Repair Shop, Military Equipment Repair Station, Machine Shop, Fabricating Shop, Assembly Department, Production Department or Quality Inspection Station!
You can rest assured, these tools are made for the long haul. Manufactured from heat-treated carbon steel with the thread sizes permanently stamped onto each gauge, it will take some serious heavy duty use before we get the opportunity to fill your next order.
Proudly made in the USA.
Features:
Each size has a nut and bolt checker on the same gauge

I love this thread checker, this one I can fit in my bag, and it has more sizes than most thread checkers.

So good I bought it twice.
I searched for three months for my old one. I had the other one for more than 10 years, perhaps 15. I couldn't live any longer without it. I bought another one. It is nearly identical. I feel like the stamping of the sizes might be a little smaller, but I am a little older. The eyes won't last forever. I guess that would be it, bigger numbers on the gauges.

Perfect
Great addition to my tool shelf. I added a spring clip and keep in hanging ready to use. Well constructed and has already saved me time and money.

Item arrived in good time, and was exactly as described. Have used several times on a rebuilding project and it has worked very well. Glad that I decided to purchase.

Great product, however, would prefer the elimination of sizes > 7/16-20 since these sizes are pretty obvious and just add size and weight to the chain.
