摘要： A drive system including a bit with a bit end configured to provide targeted frictional engagement with a fastener. The bit end has an outer leading wall tapered with respect to the bit end longitudinal axis at a leading wall angle selected from leading wall angle values ranging within a leading wall angle tolerance band and the fastener has an inner recess wall tapered with respect to the fastener longitudinal axis at a recess wall angle selected from recess wall angle values ranging within a recess wall angle tolerance band, wherein the leading wall angle values within the leading wall angle tolerance band and the recess wall angles values within the recess wall angle tolerance band do not overlap when the outer leading wall contacts the inner pilot recess wall at a targeted focal area to achieve a desired level of frictional engagement between the pilot end and the fastener.

摘要： A drive system with full surface drive contact. The drive system tends to maximize the surface contact pattern or area at typical bit-recess reaction (drive) torque values, thereby tending to minimize bit-recess surface contact stresses, coating damage, recess ream and premature bit fatigue failure. The drive system comprises a fastener and/or bit having drive surfaces formed of either polygon involutes or a single arc construction. A punch is also provided for forming a recess in either the fastener or the bit, wherein the punch has corresponding surfaces.

摘要： A connecting element, preferably for fastening a wheel, or rim, to a hub of a vehicle, includes a body having a respective outer perimeter surface which extends along a respective imaginary profile, in particular an imaginary circular profile, there being formed, at the perimeter surface, respective elements for the engagement of corresponding elements or tool for screwing and/or unscrewing the connecting element, and screw thread elements for fastening, preferably to the vehicle hub. The engagement elements include a plurality of perpendicularly extending and circumferentially distributed engagement troughs which are recessed relative to the imaginary outer profile and each being separated from the adjacent trough by a respective outer perimeter transit zone. The outer transit zone has a width (r) which is less than the width (i) of the trough, and in particular, a width (r) which is less than half the width of the trough.

摘要： A recessed fastener includes a head with a top face and a drive socket, a shank extending downward from the head, and threads helically around the shank. The drive socket has a bottom and drive walls extending upward therefrom. The bottom meets the drive walls at a bottom border. The drive walls meet the top face at a top border. The bottom border and the top border have respective first and second corners. The first corners are rotatably offset relative to the second corners. A joining line is connected between each first corner and each second corner, and one drive wall formed between two adjacent joining lines is in a spiral form. The spiral drive walls leads a driving tool toward the bottom to produce an automatic downward pressing force which facilitates the close engagement, thereby obtaining a quick driving operation, an increased driving power and a labor-saving effect.

摘要： A screw includes a head having a top surface where a drive socket and drive regions are recessedly formed. Each drive region has two non-parallel side walls and two different drive walls. One drive wall is connected to the side walls to form a groove communicating with the drive socket. The other drive wall is connected between two adjacent side walls of two adjacent grooves. At least one of the drive walls slopes downwards from the top surface at a slope of at least 1 degree. Each side wall connecting between the drive walls deviates inwards by an angle difference of at least 1 degree. The slope and the inward deviation of the walls receive a driving tool firmly to prevent a swinging problem and enhance the torque transmission. A punch adapted to form the recessed screw also facilitates a long-term production without losing the accuracy thereof.
摘要翻译：螺钉包括具有顶表面的头部，其中驱动套筒和驱动区域凹入地形成。每个驱动区具有两个不平行的侧壁和两个不同的驱动壁。一个驱动器壁连接到侧壁以形成与驱动器插座连通的凹槽。另一个驱动壁连接在两个相邻凹槽的两个相邻的侧壁之间。驱动壁中的至少一个以至少1度的斜率从顶面向下倾斜。连接在驱动壁之间的每个侧壁向内偏移至少1度的角度差。壁的斜率和向内偏差可以牢固地接收驱动工具，以防止摆动问题，并增强扭矩传递。适于形成凹入螺钉的冲头也有助于长期生产而不失去其精度。
