作为一单件的整体零件提供了一自锁紧固件,由可变形的塑料制成。自锁螺纹紧固件包括一头部和一从头部轴向延伸到自由端的螺纹杆部。螺纹杆部上在螺纹内一体地形成有锁定材料。在旋入螺孔时该锁定材料变形。锁定材料变形就在自锁螺纹紧固件和带螺孔的零件之间产生紧配合,锁定
A self-locking fastener is provided as a one-piece, unitary part made of deformable plastic. Self-locking threaded fasteners include a head and a threaded shank extending axially from the head to the free end. A locking material is integrally formed on the threaded shank within the thread. The locking material deforms when screwed into the screw hole. Locking material deformation creates a tight fit between self-locking threaded fasteners and threaded parts, locking
