The difference of NEWSCREW 304 316 Stainless steel Self Tapping Screw and self drilling screw?
There are three main differences: usage, purpose and appearance.
1) In the method of use, self-tapping screws cannot be drilled multiple times, otherwise it is easy to slip the wire. Compared with stainless steel drill end, it can directly drill into the material, which saves installation time.
2) In use, self-tapping screws can only be used on some non-metallic or soft foundations. This kind of screw can be fixed on the material. For stainless steel drilling screws, it can be used on materials with higher hardness. Therefore, stainless steel Drill tails perform better than self-tapping screws.
3) In terms of appearance, the tail of the self-tapping screw is generally pointed, and the texture is relatively hard, and the front part has a corresponding taper. But for stainless steel drill tails, the head is a drill bit that can drill holes
NEWSCREW 304 316 Stainless steel Self Tapping Screw is used for wood, metal, and brick. These screws cannot drill through metal and require a pilot hole to be pre-drilled before
