Is 3/16" machine screw equivalent to a #10?

Reference a drill tap chart. Numbers are wire gauge sizes that fall between inch sizes, well above 3/16 inch too. There are very slight differences in major and minor diameters of the threads produced. That chart will show different drill sizes required including those number size drills that fall between the common inch size drills for 3/16 and/or #10 machine threads. ( NOBODY will have the number size drills in stock ). Anyway... For general purposes, mechanic, carpenter, doctor, lawyer, Indian chief, butcher, baker, candlestick maker, 3/16 inch machine screw thread is #10 machine screw thread be it either 24NC or 32NF. Exactness comes into play where the engineer calls out one or the other on a blueprint. Substitution can cost you the contract.
