NEW! PHEINOX 316 Stainless Steel Screws for your toughest applications…
UberGrade now becomes Marine Grade!
PHEINOX stainless steel screws are made from only the best grade of stainless steel wire, 316. The unique characteristics of the PHEINOX 316 wire give our stainless steel screws unmatched performance, by maximizing both torque and increasing bending strength. GRK’s patented fastener lineup is available in a wide range of our structural, framing and interior screw varieties and are engineered to deliver exceptional and lasting performance. The New PHEINOX 316 stainless steel screws will provide the ultimate in anti-corrosion, all-weather protection everywhere and anywhere you need a fastening solution that’s impervious to the elements!.
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.
Fin/Trim™ screws are also available in white powder coated finish to blend in with white wooden trim boards.
*FOR BEST RESULTS, TRIM™ SCREWS SHOULD BE DRIVEN AT HALF SPEED. TO PROLONG THE LIFE OF THE #10 BIT, DO NOT USE AN IMPACT DRIVER ON THE #8 TRIM™ HEAD SCREW.
