GRK Pheinox™ R4™ Stainless Steel Screws
|Premium 305 stainless steel screws from GRK are the ultimate for corrosion-free outdoor performance, which is why they come with a lifetime warranty against rust and staining. Each screw features an underhead with saw-blade like cutting teeth and six self-contained cutting pockets, which transport drill dust away from the edge of the screw hole while cutting a perfectly clean hole. The screw head closes the hole off with precision, leaving no damaged fibers around the head. Because of the angle on the underside, the screw also fits perfectly into the pre-countersunk holes of hardware fittings such as hinges or locks.Technical Details:High grade 305 stainless steel screws.No pre-drilling unless material requires it.Self countersinking heads.Starhead recess / non-stripping heads.Can be used with fibrous materials.Robust threads.Works well in wood, particle board, plastic, sheet metal, cement fiberboard, composite decking, wood decking, and melamine.
