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; listed here) or metric (blue spacers; #50751, sold separately). 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.

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

Handy and work great. Just wish they had more thread pitches available.
Bought both tiny and normal size. Wish they had more thread pitch sizes available. Also wish they were on a cable that could be opened up to remove the individual testers. Otherwise they work great and are very convenient.

One of the better thread gages
Review for Imperial Mini set.. Excellent surface finish, laser etched sizes. Male and female gages have nice chamfer to reduce chance of cross-threading. I checked the male ends against another thread gage - all threads are accurately cut. On the down side, the set is not complete - it does not include 4-36 and 5-44.
Wire holder is longer than other sets, making it somewhat easier to use. Best application is for checking a loose nut or screw - the wire makes it difficult to check a thread on something that you can't easily hold in your hand and turn.the part.

After 35+ years in the automotive industry, I have cans full of loose nuts & bolts. Maybe now I can finally get busy and get them all sorted.

always wanted to know sizes of small bolts and couldn't tell until i saw this tool
Stephen on Jul 12, 2017
I'm always "guessing" what the correct diameter and pitch is on various projects. Hopefully, these will take way the guesswork.
