Applications and Benefits:
Self-drilling screws have advantages over conventional screws in that they eliminate the need to drill a pilot hole before insertion. This can save time and effort in many fastening applications, while delivering the same security and versatility of a conventional screw.
Self-drilling screws should always be installed using a power-driver and are therefore particularly suited to fast production environments. They can be used in light and heavy gauge sheet metals, soft plastics, etc, and are ideal for applications in heating and air conditioning, metal, and fiberglass fabrication industries.
Self tapping screws VS. Self drilling screws
The difference between self-tapping and self-drilling fasteners is that self-tapping screws will tap a hole into a soft material, self-drilling screws can drill a hole into anything from metal to wood meaning no pilot hole is needed.
Roofing:
Self-drilling screws for metal roofing are specially designed with a washer to form a tight seal when fastening. As with all self-drilling screws, they have a drill bit formed point that makes inserting them quick and easy.
