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.
