Tapping screws (also called self-tapping screws) are threaded fasteners designed to cut or form their own mating threads in materials like metal, plastic, or composite, eliminating the need for pre-drilled holes or tapped threads. They are widely used in automotive, electronics, construction, and machinery for efficient assembly.
Self-Creating Threads:
Sharp cutting edges or flutes on the thread profile (e.g., Type B, Type F) carve out material to create matching threads.
Drive Types:
Hex head (ISO 4762): High torque resistance, suitable for heavy-duty applications.
Phillips/Pozi drive (ISO 7049): Common for light-to-medium loads.
Torx drive: Anti-camout design for precision assembly.
Point Styles:
Type A (Sharp tip): For soft materials (plastic, wood).
Type B (Blunt tip): For thin metal sheets (e.g., DIN 7981).
Type C (Drill point): For thicker metals, includes a self-drilling tip (e.g., TEK screws).
