Whether you're organizing loose hardware or trying to identify a specific thread pitch so you can purchase replacements, the Thread Detective is the perfect tool for the job. Sets are available in three size ranges: Mini, Original and Jumbo. Each of these sets is in turn available in either imperial (red spacers; #53816, sold separately) or metric (blue spacers; listed here). All sets feature clearly marked gauges for quick identification of the size and thread pitch of both nuts and bolts. One end of each gauge checks the nuts, while bolts can be checked by threading them into the other end. Each set of gauges is strung together onto a wire lanyard that can be hung from a nail for convenient storage.

Now it is easy to find the right metric thread size. Much needed in the shop!

Much quicker and more certain than thread gauges.
I used to teach a class where we measured threads via thread gauges. Those types are only “2-D” and some metric and standard threads look VERY similar. These Thread Detectives are 100 times better than gauges. I had often envied setups for thread checking at home centers and auto parts stores. Now I can do this for myself, and can be confident that fasteners that I order will be the correct fit. Also, if I find a random connector on the workbench, I can put it in with similar threads.

I have not had to use it yet, but being able to carry a thread refference to my work and being able to check a thread on the workpiece is a great help.

Just what I need
The clerk did not have one in the store but offered to have one mailed to my house without any extra charge. Great service.

Useful and sturdy
The metal thread gauges are superior to the plastic ones when attempting to thread the incorrect size. These are well built.
