FSA T47 Threaded Bottom Bracket

Think of T47 as a larger version of traditional, and well-loved BSA threaded BB shells. T47 bottom bracket shells actually start life as standard 46mm inner diameter shells and are then threaded to M47x1.0mm. Much like a BSA shell, the right, or drive side, of the shell is left hand thread, and the left side, or non-drive side, of the shell is right hand thread.
