Market Advantage
Corrosion life that matches the building envelope. A2/A4 stainless bodies hold up in coastal, marine, and industrial atmospheres where coated carbon steel fails years early, protecting the reputation of the whole installation.
One-pass installation. The hardened drill point cuts through light-gauge steel without pre-drilling, saving a full step on every fixing and shortening cycle times on site.
Washer head does double duty. The integrated flange spreads clamp load evenly, while an optional EPDM bonded washer delivers a watertight seal against leaks in roofing, cladding, and exterior assemblies.
Low total cost of ownership. Higher upfront than carbon steel, but eliminates callbacks, rework, and premature fastener replacement in exposed or humid service-the savings show up after installation, not just at the counter.
