What is a Drill Screw
No pilot hole is required during installation. It is an advanced version of the tapping screw.
It is capable of independently drilling a pilot hole, forming threads, and driving to full fastening.
The drill point at the tip is sharp, and the threaded portion has a similar shape to tapping screws and tapping bits.
Specific applications are proposed based on the combination of the head, screw tip, and shank portion.
