Tapping screws are commonly used for connections between thin metal plates.When connecting, first make a screw in the bottom hole of the connector, and then screw the self-tapping screw into the bottom hole of the connector.

Carbon steel tapping screws should be carburized, stainless steel tapping screws should be solution hardening.Self-tapping screws meet the standard requirements of mechanical properties and performance.Still have is the product surface treatment, generally for electroplating treatment.

What are the characteristics of tapping screws?

1. Usually made of carburized steel (99% of all products).It can also be made of stainless steel or non-ferrous metals.

2. The surface of tapping screw needs surface protection treatment, usually electroplating treatment.The surface of some products requires a phosphate treatment (phosphate).

3. The product has high surface hardness and good core toughness.”Rigid inside and outside.”This is the main characteristic of self – tapping screw performance requirements.

4. Cold HEAD process is adopted for production.It is recommended to use high speed cold head machine and high speed wire rolling machine or high speed planetary thread machine.

5. The product surface needs surface protection treatment, usually electroplating treatment.The surface of some products must be treated with phosphate (phosphating), such as wall panel tapping screws are mostly treated with phosphating.

The above is the introduction of the characteristics of self tapping screws.I hope everyone can help you by understanding the characteristics of self-tapping screws.
