Thread Checker Patent Logo
 
The Metric 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
  • Thread sizes are permanently stamped (in white) onto each gauge
  • Individual gauges are black oxide plated steel
  • The individual gauges rotate freely on the wire cable for fast thread verification
  • Wire cable with loop for convenient hanging

    Eliminated confusion
    I had a large box full of metric nuts and bolts, leftover from my Japanese cars. Thanks to the Checker they have all been separated by size and placed in appropriate storage bins for reuse. I found it very useful that a variety of thread pitches could be easily identified, especially with the smaller sizes.

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

    The service was awesome. The product is of very good quality. Have used it a multitude of times as I am restoring my car and as part of the process includes replacing all old/ugly hardware.
