3/8" X 4-1/2" Stainless Steel Sheet Metal Screw, Self-drilling

This stainless steel sheet metal screw is engineered for reliable fastening of thin-gauge metal sheets, wood, fiberglass, and composite materials. The 3/8" diameter and 4-1/2" length provide deep penetration and a secure grip on lightweight substrates. Its self-drilling point cuts through materials effortlessly, eliminating the need for separate pilot holes on most applications and reducing installation time while minimizing the risk of material splitting.

The corrosion-resistant stainless steel construction ensures long-term durability in humid environments and outdoor conditions, making it ideal for both indoor household maintenance and exterior repairs. The precision-engineered flat head design sits flush with the work surface, reducing snagging hazards and delivering a clean, professional appearance while maintaining balanced pressure distribution across delicate workpieces.
