Metal Self-Tapping Lock Screws

Self-Tapping screws can tap their own hole as they are driven into a material. This eliminates the need for a pre-drilled hole. They often include a locking feature to prevent the screw from loosening under vibration or stress. Typically made from various metals such as steel, stainless steel, or brass to provide strength and resistance to corrosion.

Applications:
Sheet Metal: Commonly used in automotive and aerospace industries for fastening sheet metal components.
Plastic: Used in electronics and consumer goods to fasten plastic parts.
Wood: Utilized in construction and furniture making.

The self-tapping screw is a self-tapping screw with a coarse thread structure. The thread section of the screw is an arc-shaped triangle. It can be screwed into the prefabricated hole of ferrous or non-ferrous metal materials and formed into an internal thread by extrusion. When the screw is screwed into the thread, its threadless rod can be made into a cylindrical or triangular shape with a diameter equal to or less than the circumscribed circle. It has the characteristics of small screw-in torque and high locking performance.

The standards and varieties of self-tapping screws in domestic fastener products mainly include five series: GB/T6560 (cross recessed pan head), GB/T6561 (cross recessed countersunk head), GB/T6562 (cross recessed countersunk head), GB/T6563 (hexagonal head), and GB/T6564 (hexagonal cylindrical head).
