GRK's Trim Head screws are an excellent choice for most fine carpentry applications, as well as window extension jambs and more. Our Trim Head screws have the smallest screw head available; with screw lengths from 1-1/4" (30mm) to 5" (125mm).
Most material splitting is prevented because of the Trim Head screw's exceptionally small head and the W-Cut thread design.
PHEINOX stainless steel screws are made from only the best grade of stainless steel wire, 305. The unique characteristics of the PHEINOX wire give our stainless steel screws unmatched performance, by maximizing both torque and increasing bending strength.
GRK recommends PHEINOX 305 stainless steel screws for applications that require superior corrosion resistance in wet environments such as decks, boardwalks, pools, and hot tubs. PHEINOXTM305 stainless is also recommended for use with cedar, red-wood and various other wood substrates that have higher acid content as well as for composite deck boards. PHEINOXTM305 stainless steel screws are recommended for applications located more than 1 mile from the coast.
