GRK GRK-17630 - WHITE RT COMPOSITE™ TRIM SCREW #8 X 2-1/2" -100bx protective boot Lightweight Design for Increased Balance:GRK has modified its innovative FIN Trim Head screw to include reverse threading under the head of the fastener. This technology makes the RT Composite Trim Screw ideal for use in composite and cellular PVC trim Based on extensive tests, GRK has found that the reverse thread helps the screw head disappear beneath the surface of the classic wood composite material, reducing or eliminating the dimple that sometimes appears when using the FIN Trim screw.
