    Abstract: A fastener includes a screw rod and a head connected to the screw rod. The head includes a driving surface furthest from the screw rod. The driving surface defines at least two driving grooves arranged around a circumference of a circle with an axis of the screw rod being the center of the circle. The driving surface forms at least two driving lobes received in each of at least two driving grooves, and the at least two driving lobes are located at the circumference of the circle around the axis of the screw rod.

    Abstract: A fastener includes a connecting portion and a head portion connected with the connecting portion. The head portion defines an engaging hole and includes a plurality of protruding teeth separately formed on an inner peripheral wall of the engaging hole, respectively, toward a central axis of the engaging hole of the head portion, and a plurality of recesses are formed between every two adjacent protruding teeth, respectively. The head portion further includes a plurality of resisting projections separately formed on the inner peripheral wall of the engaging hole, toward the central axis of the engaging hole, and received within the corresponding plurality of the recesses of the head portion, respectively. The present disclosure further provides a driver engaging with the fastener and a punch producing the fastener.

    Abstract: A fastener includes a connecting portion and a head portion coaxially connecting with the connecting portion. The head portion defines an engaging hole which includes a main engaging hole and one or more auxiliary engaging hole coaxial with the main engaging hole. A plurality of auxiliary engaging teeth are separately formed on an inner peripheral wall of the engaging hole, toward a central axis of the engaging hole of the head portion, thereby forming the auxiliary engaging hole. A plurality of main engaging teeth are coaxially formed on the auxiliary engaging teeth, toward the central axis of the engaging hole respectively, and are positioned at the base of the engaging hole. The fastener provides two bearing surfaces on which a driver can act upon, and the present disclosure further provides the driver to engage with the fastener and a punch for producing the fastener.

    Abstract translation: 紧固件包括连接部分和与连接部分同轴连接的头部。 头部限定了包括主接合孔和与主接合孔同轴的一个或多个辅助接合孔的接合孔。 多个辅助啮合齿分别形成在接合孔的内周壁上，朝向头部的接合孔的中心轴线形成，从而形成辅助接合孔。 多个主啮合齿同时地形成在辅助啮合齿上，分别朝向接合孔的中心轴线形成，并且位于接合孔的底部。 紧固件提供两个支承表面，驾驶员可在其上作用，并且本公开进一步提供驾驶员与紧固件接合和用于产生紧固件的冲头。
