Exterior-Grade Self Drilling Screws with Enhanced Corrosion Protection
These 22mm x 4.8mm low profile wafer head self drilling screws are designed for fastening external sheet metal and steel frame assemblies. The larger 4.8mm diameter increases pull-out strength, while the 22mm length is ideal for penetrating through layered or thicker substrates.
Engineered with a silver organic coating (500+ hours salt spray resistance), these screws are suitable for outdoor and semi-exposed applications. The self-drilling tek point eliminates the need for pilot holes, and the low-profile wafer head ensures a clean, flush finish that won’t snag or distort materials.
This exterior-grade screw is ideal for high-moisture areas and outdoor fixtures where corrosion resistance is critical.
Typical uses: external signage, building cladding, cable tray supports, HVAC systems, and steel fencing brackets.
