Stop Guessing Thread Sizes
Identify common metric and SAE threads faster with an organized gauge set for bolts, nuts and threaded holes.
Upgraded Thread Checking Set
Every thread checker is inserted into well cut foam that holds them firmly in place to prevent them from bouncing around in the box, but not so tight that you can easily remove them. Easier to use than connected nut or thread checkers, because you no longer have to carry a whole bunch of gauges to measure individual screws or nuts and can reach any tight spot.
Identifies Benefit
Identifies common nut and bolt thread sizes quickly.

Metric Design
Metric and SAE references reduce workshop guesswork.

Individual Convenience
Individual gauges support checking fixed bolts and threaded holes.
Improved Efficiency
Just screw the nut or bolt into the screw thread gauge, it takes you a few seconds to check the size. Also, this nut and bolt gauge is especially well suitable for the distinguish between similar inch and metric threads.

Organized Everyday Value
Organized red and blue case keeps the set together.
