How much do you know about self-tapping screws?

Editor:Zhejiang New Shengda Fastener Co., Ltd. │ Release Time:2022-05-28 

The product has high surface hardness and good core toughness. This is a major feature of the performance requirements of self-tapping screws. If the surface hardness is low and the toughness of the core is poor, the screw will be easily broken during use. Therefore, "inner softness and outer rigidity" are the requirements for self-tapping screws to meet the performance requirements. So, what processing will the self-tapping screw production process with unique characteristics go through?


Carbon steel self-tapping screws are carburized, and stainless steel self-tapping screws are solution hardened.  Self-tapping screws meet the mechanical properties and performance requirements of the standard. There is also the surface treatment of the product, generally electroplating.
