When working in the laboratory, I often end up with unknown screws. I could use a regular screw gauge to figure out the thread profile, but often when working with robots I don't know if the screw is metric or imperial and some of the profiles are fairly close.

I use the SCREW CHEK'R screw gauge to solve this problem. This handy tool that not only identifies the screw, but also lists the drill number for threaded and through holes.

Imperial (English)
Metric 2mm - 7mm
Metric 8mm - 14mm
