What Are Self-Tapping Screws Used For?
Quick answer: Self-tapping screws create or form a mating thread as they are installed in a prepared or suitable hole. They are used in sheet metal, plastics and other materials within the fastener’s rated capacity.
Key points
- Thread-forming screws displace material; thread-cutting screws remove material.
- Some self-tapping screws need a pilot hole, while self-drilling screws add a drill point.
- Performance depends strongly on material thickness, hardness and hole size.
How to choose or use it
Use the manufacturer’s pilot-hole recommendation and keep the driver square. Avoid repeated removal when the formed thread is not designed for it. For thin sheet, stop as soon as the head seats to avoid stripping the newly formed thread.

Installation and safety checklist
- Confirm the receiving material, hole preparation and mating thread.
- Verify diameter, pitch, length, head, drive, material and finish.
- Use a well-fitting tool, keep it aligned and tighten only to the required seating or specified torque.
- For structural, overhead or safety-critical joints, follow the approved design, code and manufacturer data.
