No.10 40mm Self-Tapping Screw – Pack of 100

A No.10 40mm self-tapping screw designed for fastening into pre-drilled holes in metal, plastic, and composite materials without requiring a nut or separate bolt. The sharp, hardened point cuts its own thread as it's driven, making installation faster and more efficient on site. Ideal for electricians, panel builders, and general construction work where speed and reliability are essential.
