GRK Fasteners RT Series 15079 Screw, #8 Thread, 2-1/2 in L, Partial Thread, Trim Head, Star Drive, Type 17 Point, Steel

GRK has modified it's innovative FIN/Trimâ„¢ head screw to include reverse threading under the head of the fastener. This technology makes the RT Compositeâ„¢ 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/Trimâ„¢ screw. The reverse thread feature is available in RT Compositeâ„¢ screws from 2 to 3-1/8 in length in both regular Climatekâ„¢ coating and in white Climatekâ„¢ coated finish to blend in with popular white exterior composite and cellular PVC trim.
