Abstract: A fastener with a recess head wherein the drive head has four lobular recess channels. Each channel comprises a first wall, a second wall, a bottom surface and a recess sidewall. The first and second walls have portions opposing each other and a constant radius of curvature to form a continuously and smoothly forming wall of the channel. A torque producing driver tool is defined with cross sectional signature substantially complementary in size and shape of the recess of the drive head of the fastener for matable engagement. A recess punch for manufacturing the fastener is also defined and comprises a punch holder and a punch pin integral with the holder.

Abstract: A drive system for a surgical fastener is composed of a drive tool with a drive tip that mates closely with the recess formed in the head of a threaded fastener. The surgical fastener has a head with a quadrilobe fitting therein which closely mates with the quardilobe tip of the tool. The cooperating drive surfaces align the fastener and tool coaxially and produce four point contact equidistant about the circumference of said fastener significantly reducing angular excursions of the fastener during placement in the bone.
