Stainless Steel Self Tapping Screws

Self tapping screw is a type of threaded fastener that is used to self tap and drill female threads into pre drilled holes in metal or non-metal materials. This type of screw is mainly used for the connection and fixation of thinner plates, such as the connection between color steel plates, the connection between color steel plates and purlins, wall beams, etc. Its penetration capacity generally does not exceed 6mm, and the maximum is not more than 12mm. The design of self tapping screws allows them to be directly screwed into materials without the need for pre drilling or tapping, greatly improving work efficiency. This type of screw is usually produced using carburizing steel, stainless steel, or non-ferrous metals, and undergoes heat treatment to ensure high surface density and good core ductility of the product. The head shapes of self tapping screws are diverse, including round head, flat head, pointed head, etc.
