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 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 our stainless steel products come with a limited lifetime warranty against staining and rusting.
GRK's FIN/Trim™ Head screws are an excellent choice for most fine carpentry applications and more. They are also ideal for the installation of window extension jambs. Our FIN/Trim™ Head screws have the smallest screw head on the market; With sizes available from 1"1/4(30 mm) to 5"(125 mm), users have plenty of choice.
The FIN/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)
FIN/Trim™ Head screws are self-tapping screws with a W-Cut™ thread design and ZipTip™.
