Hi all,
Tapping is the operation of machining a thread inside a bore.
A tapped hole is the complementary shape of a screw or threaded rod. Technically, it is a smooth hole in which a thread improperly called a screw thread takes place.

I hope that one day someone will create a script to do tapping, screwing, "Taraudage" in French, with chamfer in mind. To complete "NutsAndBolts".
For the moment I do it manually with two solids: a screw created with "NutsAndBolts" without nut or washer and a chamfer, then a Boolean operation of subtraction. Alright, it's working fine. Waiting for a "Tapping" script.
