The product has high surface hardness and good core toughness. This is a major characteristic of the performance requirements for self tapping screws. If the surface hardness is low and the toughness of the core is poor, the screw is easy to break during use. Therefore, "internal flexibility and external rigidity" are the performance requirements of self tapping screws. So, what are the treatments for the production process of self tapping screws with unique characteristics?
Carbon steel self tapping screws need to undergo carburization treatment, while stainless steel self tapping screws need to undergo solution hardening treatment. Self tapping screws meet the mechanical and functional requirements of the standard. Another aspect is the surface treatment of the product, usually electroplating treatment.
