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. Our special composition of PHEIONX™ 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 our stainless steel products come with a limited lifetime warranty against staining and rusting. GRK has modified its innovative FIN/Trim™ Head Screw to include reverse threading under the head of the fastener. After extensive testing, GRK has found that the reverse thread on the RT Composite™ Trim™ Head Screw helps the screw disappear beneath the surface of the wood composite material, reducing or eliminating the dimple that sometimes appears when using the FIN/Trim™ Screw.
GRK's RT Composite™ Trim™ Head Screws are ideal for most fine carpentry applications, and are recommended for composite decking projects. The reverse thread feature is available in sizes from 2" to 3"1/8. The RT Composite™ Trim™ Head screw's exceptionally small head, along with the W-Cut™ thread design, prevent most material splitting. Pre-drilling is only necessary if the building material's limitations require a pilot hole to be drilled. (Always consult wood supplier's / manufacturer's recommendations)
