Hillman Tap N' Seal self-piercing screw for fastening metal roofing and metal siding to wood framing in pole barns and similar metal-building applications. The needle point pierces metal and wood in one shot - no pilot hole needed - and the steel-backed flexible neoprene washer compresses to seal the fastened joint against wind-driven rain and snow melt.

• Finish: Gray ceramic-coated zinc plating - exceeds 1000-hour salt spray testing
• Fastens metal panels to wood and fiberglass panels to wood
• Pack: Retail 1 lb box - approximately 107 pieces per box

Tip: #10 x 1-1/2" is the workhorse pole barn screw - 26- or 29-gauge corrugated or rib-panel steel into nominal 2-by wood purlins, sidewall girt screws on metal buildings, and standard metal roofing-to-truss attachment in residential and agricultural builds. Retail 1 lb box covers small repairs, single-panel replacements, and touch-up work. Drive heads flush so the neoprene washer compresses evenly against the panel - over-drive and the washer extrudes out (no seal); under-drive and the washer doesn't load (still no seal). For maximum corrosion service, match the Hillman gray-ceramic Tap N' Seal screw with painted or galvalume-finished panels rather than bare galvanized - the gray ceramic finish is engineered to color-match common roofing finishes from a distance.
