DESCRIPTION

Feature

(1) 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.

(2)Surface treatment.

The surface of the product needs surface protection treatment, generally electroplating treatment. 

Some products have to be phosphate treated (phosphating), such as wallboard self-tapping screws 

are mostly phosphating.

(3) 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.
