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.
A fastener system includes a fastener and a driver, each of which have three alternating lobes and troughs that define the drive surfaces. The three alternating lobes and troughs are each defined by an outer radius portion, a drive side transition, an inner transition radius, and a reverse drive portion. The fastener recess and the driver each also have a side wall defined by the outer transition radius that tapers at a taper angle relative to the rotational axis. The fastener side wall may taper at about 60. The driver side wall may taper at about 60. Alternatively, the driver side wall may taper at an angle at least 10 less than the taper angle of the recess side wall, such as 42. The drive side transition defines a drive angle which may be between 0 and 5.
