GRK RT Composite Trim Screws

GRK RT Composite Trim Screws are ideal for the installation of composite and cellular PVC trim (Azek, Kleer, Koma). They leave a clean look as the tiny heads disappear when the fastener is countersunk into the material. The RT Composite Trim Screw features a Climatek coating, which reduces or eliminates the dimple that appears when it is fastened. The reverse threading under the head of the fastener helps the screw head disappear beneath the surface of the material while preventing mushrooming and eliminating dimples for a smooth, even surface.
