PHEINOX™ Stainless Steel Screws (305 stainless steel grade) are another first from GRK Fasteners. PHEINOX™ Screws provide a reasonably priced alternative when only stainless steel will do.
Their special composition of PHE™ stainless steel is one of a kind. It is hardened and rust free and is of the quality you come to expect from GRK products. All of their stainless steel products come with a lifetime warranty against staining and rusting.
The R4™ is a multi-purpose screw that can be used in all woodworking and plastic applications. Because the head has a 90 degree angle at the underside, the screw fits perfectly into the pre-countersunk holes of hardware fittings such as hinges or locks.
