Features of Self-Drilling Screws:
The special design of the end of the drill point allows the self-drilling screw to integrate three functions: Drilling, Tapping, and Locking on one screw. Its surface hardness and core hardness are higher than ordinary self-tapping screws. The biggest advantage of the self-drilling screw is it can save construction time and cost-effectiveness. Therefore, the field of self-drilling screw application has become wider than we expected before.
Self-drilling screws could reduce the working process and are usually used in construction, decoration, roofing, glass, and other fields. Therefore, self-drilling screws are also called window screws and roof screws.
- Drill — The drill point of the end tail can drill the surface of the mating parts directly.
- Tapping — Tapping in the hole directly to create internal threads.
- Lock — No need to tap holes in advance to lock objects
