The hexagonal flange head self-tapping screw refers to a head with a hexagonal head, a flanged head, a self-tapping screw with a self-tapping type at the tip, and a self-tapping screw with a thread.

Hexagonal washer head self-tapping screws

1. Generally made of carbon steel (99% of total production). Stainless steel can also be used.

2. Hexagonal washers with self-tapping screws must be heat treated. Carbon steel self-tapping screws must be carburized, and stainless steel self-tapping screws must be solid solution hardened. In order to achieve the mechanical properties and performance properties required for the self-tapping screws.

3. Hexagonal washers Self-tapping screws have high surface hardness and good core toughness. That is, "inner soft outside just." This is a major feature of the performance requirements of hexagonal washers with self-tapping screws. If the surface hardness is low, it will not be screwed into the base; if the core has poor toughness, it will not be used if it is broken. Therefore, "internal soft outer steel" is a very important requirement for hexagonal washers with self-tapping screws to meet the performance.

4. Hexagonal washers Self-tapping screws require surface protection treatment, usually electroplating. Some products have to be phosphate treated (phosphating), such as wallboard self-tapping screws are mostly phosphating.

5. Production by cold heading process. It is recommended to use a high speed cold heading machine and a high speed thread rolling machine or a high speed planetary thread rolling machine. The emphasis on high speed is to ensure product quality. Only the head of the self-tapping screw produced by the high-speed machine is formed, and the thread quality is high.
