high-low thread screw must be heat-treated. Carbon steel high-low thread screw must be carburized, and stainless steel self tapping screws must be treated by solid solution hardening. It can also be made of stainless steel or nonferrous metal. The mechanical properties and service performance of high-low thread screw meet the standard requirements. The hardness of the surface is high and the toughness of the core is good. That is, "inside and outside". This is a major feature of the performance requirements of the high-low thread screw.
