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 the use of its PHEINOX™ stainless steel fasteners in tropical wood, cedar wood, pool, hot tub, sauna and seaside applications, as well as deck applications in areas with large daily temperature variances. The ultimate finish for superior all wather corrosion protection.
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.
