The Self-tapping Screw is a high-performance industrial fastener specifically engineered for the assembly of metal sandwich panels (Sound, Energy, and Insulation types) to steel or timber sub-structures. Crafted from Carburized Steel, these screws undergo a thermal hardening process that creates a dual-property metal: a glass-hard surface for superior drilling through thick steel plates and a tough, ductile core to resist snapping under structural load.
