Short machine taps for BA, British Association thread

BA is the British series for very small threads. The size is given as a number — the higher the number, the smaller the thread. A short machine tap produces the finished thread in one pass. It replaces the three-piece set wherever speed matters, and works by hand as well as in the machine.
