Abstract: A torque transmission driver has a first end portion adapted to receive and transmit torque from a torque generation source, and a second end portion including a shaped tapered bit having drive surfaces with an alternating series of five or six lobes and troughs about a rotational axis, having a taper angle between 15 and 65 from the rotational axis operable to engage corresponding drive surfaces in a plurality of at least two size fasteners, the tapered drive surfaces of the bit comprising a first tapered portion operable to engage drive surfaces of a first sized fastener and a second tapered portion operable to engage drive surfaces of a second sized fastener, the drive surfaces of the second sized fastener being larger than the drive surfaces of the first sized fastener. The taper angle may be nominally 52 from the rotational axis.

Abstract: A torque transmission driver is disclosed. The torque transmission driver has a main body having a first end portion and a second end portion, where the first end portion is adapted to receive and transmit torque from a torque generation source, and the second end portion is opposite the first end portion and has a key shape adapted to fit a recess in a fastener and has a protruding lead end having a taper between 10 and 30 and different in shape than the key shape with at least a portion of the protruding lead end substantially coextensive with the major dimension of the key shape. A torque transmission driver adapted to drive a small fasteners is also disclosed where the key shape is adapted to fit the recess of the small fastener.
