A fastener system includes a fastener and a driver, each of which have three alternating lobes and troughs that define the drive surfaces. Each alternating lobes and troughs is 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 a rotational axis. The fastener side wall may taper at about 60&#xb0;. The driver side wall may taper at about 60&#xb0;. Alternatively, the driver side wall may taper at an angle at least 10&#xb0; less than the taper angle of the recess side wall, such as 42&#xb0;. The drive side transition defines a drive angle, which may be between 0&#xb0; and 5&#xb0;.

Tapered lobular driver and fastener

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&#xb0; 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&#xb0; from the rotational axis.

A swivel hanger system includes an anchor member with an anchor head disposed at an end of the anchor member and an elongated body, where at least a portion of the elongated body is configured to be inserted into a support member when the system is connected with the support member. The system also includes a swivel member with an open end extending to a hollow interior of the swivel member, where the open end is configured to rotatably couple with the anchor head such that the anchor head is located within the hollow interior and the elongated body extends through the swivel member open end. The system further includes a stop structure to limit an insertion distance at which the anchor member is inserted into the support member.

Driver

A self-clinching fastener suitable for connection to a member having a shank of a diameter less than a head portion, the head portion having at least eight lands extending outwardly along the underside of the head portion spaced about the shank, each land having a face surface extending beyond the shank to a diameter less than or equal to the radius of the head portion, the width of the lands reducing from adjacent the shank toward the radius of the head portion. The fastener further includes an axial annular engagement groove having a diameter larger than the shank, the annular engagement groove axially extending from the lands to a retaining collar adjacent the shank, the groove adapted to relieve material of a member on installation by receiving material as the lands in the underside of the head portion mechanically interlock with the member.
