Bi-Metal self-tapping screw austenitic stainless steel

Torx drive hex washer head BI-METAL Self Tapping Sheet Metal Screw w/ Bond Seal Washer Made of Stainless Steel 304+410 provides superior corrosion resistance

Manufactured from SS 304 (A2) grade Austenitic Stainless Steel for maximum corrosion resistance with hardened ss410 or carbon steel 1022 sharp tip for maximum drilling performance.

Fastens sheet metal fast: used extensively for side-lap stitching on exposed fastener metal panel roofs.

Assembled with EPDM (Ethylene, Propylene and proportion of Diene) bonded washer for safe sealing of every screw

Environmental protection ruspert coating, which has a 1000-1500 hours’ salt spray test time and multi-color matching, it provides a better barrier to prevent the corrosion.
