Pheinox RSS 305 Stainless Steel Screws by GRK Fasteners

For a lag screw alternative that will stand up to even the harshest elements but doesn't require pre-drilling, choose PHEINOX RSS Stainless Steel Screws from GRK. They're made of hardened 305-grade stainless steel and are perfect for interior or exterior use. Among the unique features of the Pheinox RSS are its built-in washer head that doesn't have sharp edges and a six-threaded CEE thread that reduces the likelihood of splitting because it enlarges the screw hole, plus it provides incredible drawing strength without a chance of rust.
