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

Self-tapping screws (No.10, 40mm length) are designed to cut their own thread as they are driven into soft metals, plastics, and composite materials without requiring pre-drilling. These fasteners feature a sharp point and helical flutes that create a thread path, making them ideal for rapid assembly in sheet metal work, panel building, and general fabrication. Essential for electricians, HVAC technicians, and metal fabricators working on-site.
