Product Description GRK RT Composite™ screw is a specially designed fastener for attaching composite and cellular PVC materials. The RT Composite has a reverse threading under the head of the fastener that helps the screw head disappear beneath the surface and eliminate mushrooming when installing Composite materials. RT Composite Screws have a Climatek™ Coating for installation in both interior and exterior conditions where exposure to moisture is intermittent and is code-approved for use in treated lumber. From the Manufacturer GRK's FIN/TRIM head screws are an excellent choice for most trim carpentry applications. They have the smallest screw head available with lengths from 1-1/4-inch to 5-inch. Most material splitting is prevented by the Trim head screw's small head and W-cut thread design. Pre-drilling is usually only necessary in extreme hardwoods like Mahogany or Ipe'. Some sizes are availabele in PHEINOX stainless steel.
