Thread Detective for Guitars, Thread Checker and Thread Identifier Specially Customized for Guitar Parts, with 14 SAE Gauges and 14 Metric Gauges

I'm barely a woodworker let alone a luthier. What i am is a Mechanical Engineer and what i needed was a thread identifier for my team. All the other ones that came up on Amazon were for size #8 or M6 and up. In the electronics and scientific products field we need small and this one is perfect for that.Yes, i know that the correct engineering way to determine a thread is to use calipers to measure major and minor diameter, as well as thread pitch and then consult the almighty tables. But as a former machinist and mechanic, I think the heart of engineering is to look for easier ways of doing things. And it rarely gets easier than taking a male-female threaded standoff that is clearly marked and fit checking my unknowns.We'll see how long "chrome plated steel" lasts but it amuses my fellow mechanical engineers that we are using luthier tools to design cutting edge molecular chemistry instruments...
