    • A coupling arrangement includes a fastener driver head and a mating tool drive socket. The fastener driver head comprises a substantially circular disc-shaped base portion, a plurality of frustoconical portions integrally formed with the base portion and concentrically located within one surface thereof. A plurality of ribs are integrally formed with the base portion and alternating with the frustoconical portions and extend axially outwardly of both the base portion and the frustoconical portions. Each of the ribs extends from a line parallel with and spaced above a given diameter of the base portion to an outer periphery of said base portion. A mating drive tool has a recessed driving head or socket substantially complementary with the fastener head for closely interfitting engagement therewith.
    • 联接装置包括紧固件驱动头和配合工具驱动插座。 紧固件驱动头包括大致圆形的盘形基部,与基部一体形成并且同心地位于其一个表面内的多个截头圆锥形部分。 多个肋与基部一体地形成并且与截头圆锥形部分交替并且在基部和截头圆锥形部分的轴向向外延伸。 每个肋从与基部的给定直径平行并间隔开的线延伸到所述基部的外周。 配合驱动工具具有与紧固件头基本上互补的凹入的驱动头或插座,用于与其紧密配合。
