VDK self-drilling screws : round head - square recess

Clim self-drilling screws are designed to assemble several metal sheets together in a single operation. They avoid the tedious and expensive pre-drilling operations needed with traditional screws. Serrations under the head of the screw also help strengthen the grip on the surface for better holding.
