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 Climatek™ coating and in white Climatek™ coated finish
to blend in with popular white exterior composite and cellular PVC trim.

Recessed Star Drive: Zero Stripping, with 6 points of contact.
Reverse Threads eliminate mushrooming.
Trim Head: for a clean finished look.
W-Cut™: Low torque, faster drive.
Zip-Tip™: No pre-drilling, faster penetration.
ESR-3201 Approved for structural application.

Kleer,™ Koma™), no pre-drilling is necessary. Climatek™ coated screws work well with CAMO system.
