摘要： A driver bit and a header punch for manufacture of screws comprising a screw comprising substantially vertical end wall portions of predetermined depth formed on an end edge portion of a bit fitting groove on a screw head, non-planar bottom portions raised from lower edge portions of the vertical end wall portions toward a center of the screw head, inclined groove portions extending from raised portions of the non-planar bottom portions toward a center of a screw neck, a substantially conical-shaped bottom surface formed on a bottom of the groove, the bit fitting groove being adapted to a driver bit, which has a blade adapted to be fitted into the bit fitting groove and has a lower edge portion of the blade adapted to abut against the non-planar bottom portions. In this manner, groove portions of a cross groove on the screw are improved in construction, whereby it is possible to effectively prevent a driver bit from coming out, prevent breakage of screws caused in the prior art, always achieve an appropriate and rapid screw fastening work even when the cross groove of the screw is broken, and to significantly enhance an efficiency in work.

摘要： A screw for snugly-fitted tightening pairs, of the type having a lobate head or a lobate-socket head (31), in which each lobe (37) is formed of one face (37') directed in a substantially circumferential manner and two other substantially parallel faces (35, 36) directed inwardly of the screw; said screw is provided with a reaction surface (33) with a tightening wrench (32). The portions of said reaction surface (33) included between two adjacent lobes are comprised each of a pair of faces (38, 39) inclined to each other to form an angle concave towards the outside of the screw, so as to constitute a reaction surface with a wrench of a polygonal profile. Such a screw can be operated to advantage either with the polygonal wrenches of the known art, or with an innovatory mating wrench of a lobate configuration.

摘要： A threaded bolt has an enlarged hexagonal auxiliary driving head and an outwardly adjoining smaller main driving head. The small driving head is dimensioned so that it will shear from the remainder of the bolt under an applied driving torque which approximates the seating torque of the bolt. Thus when the bolt is screwed into a workpiece by applying a driving tool to the small driving head, the small head shears from the bolt when the bolt is fully seated and tightened in an assembly under a tensile load approximating the design load of the bolt. The large hole is used in removing the fastener from the assembly.
摘要翻译：螺栓具有扩大的六边形辅助驱动头和向外相邻的较小的主驱动头。小的驾驶头的尺寸被设计成使得它将在施加的驱动扭矩下从螺栓的其余部分剪切，该驱动扭矩接近螺栓的座位扭矩。因此，当螺栓通过向小型驱动头施加驱动工具而将螺栓拧入工件时，当螺栓完全就位时，小的头部从螺栓剪切并在紧固螺栓附近的拉伸载荷下紧固在组件中。大孔用于从组件中取出紧固件。
