GRK FIN/Trim Screws are an excellent choice for most fine carpentry applications, as well as window extension jambs, joining cabinets, and more. A combination of the smallest screw head available and code-approved structural performance means the most secure, concealed fastening in the industry. FIN/Trim 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.
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.
