Product：

The product surface hardness is high, the core toughness is good. That is, "soft inside strong outside". This is a major feature of tapping screw performance requirements. If the surface hardness is low, it can not be screwed into the matrix; If the core toughness is poor, a twist will break, can not be used. So "inside soft outside steel" is self-tapping screw to meet the use of performance, very important requirements.

The surface of the product needs surface protection treatment, generally electroplating treatment. Some product surface must be treated by phosphate (phosphating), such as wall panel self - tapping screws for phosphating.
