GRK Fasteners 15083 #8 x 3-1/8" Bulk RT Composite Exterior Trim Screws (2,500/Box)
Thread Design Prevents Mushrooming
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.
The reverse thread feature is available in RT Composite screws from 2" to 3-1/8" in length in both regular Climate coating and in white powder coated finish to blend in with popular white exterior composite and cellular PVC trim.
