GRK has modified its innovative FIN/Trim™ Head Screw to include reverse threading under the head of the fastener. After extensive testing, GRK has found that the reverse thread on the RT Composite™ Trim™ Head Screw helps the screw disappear beneath the surface of the wood composite material, reducing or eliminating the dimple that sometimes appears when using the FIN/Trim™ Screw.
GRK's RT Composite™ Trim™ Head Screws are ideal for most fine carpentry applications, and are recommended for most composite decking projects and climates. The reverse thread feature is available in sizes from 2" to 3"1/8.
The RT Composite™ Trim™ Head screw's exceptionally small head, along with the W-Cut™ thread design, prevent most material splitting. Pre-drilling is only necessary if the building material's limitations require a pilot hole to be drilled. (Always consult wood supplier's / manufacturer's recommendations)
RT Composite™ Trim™ Head screws come with 1200+ salt spray hours Climatek™ corrosion protection. This will come in very handy when using our Trim™ screws in composite decking.
FOR BEST RESULTS, TRIM™ SCREWS SHOULD BE DRIVEN AT HALF SPEED.
