Self tapping screw is simply a screw that can tap itself. The difference between self-tapping screws and ordinary screws is that ordinary screws must have a processed screw hole to screw in. Self tapping screws do not need to screw in at the same time their own tapping. In order to achieve their own tapping purposes, the hexagonal drill tail screws are generally pointed, in order to facilitate squeezing into the object to be screwed into.

Although there are many types of tapping screws, they all have the following similarities:

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.
