• 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"
