    The cross recessed pan head self-tapping screws are composed of three parts: the head, the rod and the end of the rod. Each self-tapping screw has four major components: head shape, wrenching, thread type, and end pattern.


  

       Head shape


  The shape of the head is varied. Round head (semicircular head), oblate head, round head flange (with pad), flat head flange (with pad), pan head, pan head flange (with pad), countersunk head, semi-recessed head, Cylindrical head, spherical cylindrical head, horn head, hexagonal head, hex flange head, hexagonal flange (with pad), etc.


  Thread type


  There are many types of threads. Self-tapping threads (wide thread), machine threads, drywall nail threads, fiberboard nail threads, and other special threads. In addition, the thread can be divided into single lead (single head), double lead (double head), multi-lead (multi-head) and high and low double-head thread.


  When using, do not need to make a bottom hole and tap the inner thread, directly screw in with the tool to lock the product. The stainless steel self-tapping screws have no dents coming out after drilling into the substrate. Because the thread of stainless steel self-tapping screws is different from the general one, the head is pointed and the tooth distance is relatively large. It is similar to the chipless wire tapping. It can be directly screwed in without tapping. Metal and plastic are usually connected by this method.
