GRK R4 Multi-Purpose 305 Stainless Screws

Description

The GRK R4 305 Stainless Screws are corrosion resistant fasteners made of a stainless steel Pheinox 305 wire for the harshest environments. These screws are countersinking that have an under head with a saw-blade like patented cutting teeth, as well as six self-contained cutting pockets. The screw head closes the hole off with precision, leaving no damaged fibers around the head. Acts like a circular saw blade, transporting the "drill dust" away from the edge of the screw hole while cutting a perfectly clean hole into even the most brittle materials without cracking any surface treatment. GRK's R4 stainless steel screws are used on applications such as in tropical woods, cedar wood, pool, hot tub, sauna and seaside applications in areas with large daily temperature variances.
