GRK’s Trim Head screws have the smallest screw head available which prevents most material from splitting. Pre-drilling is only necessary if the building material’s limitations require a pilot hole to be drilled (ie. Hardwoods like Mahogany).
- For use in all trim applications, most composite decking and most fine carpentry applications (as well as window extension jambs and more)
- No pre-drilling
- W-Cut thread design
