GRK FIN/Trim Head Screws are an excellent choice for most fine carpentry applications, as well as window extension jambs and more. GRK FIN/Trim Head screws have the smallest screw head available and range in length from 1-1/4-Inch to 5-Inch. Almost all material splitting is prevented because of the Trim Head screw's exceptional small head and the W-cut thread design. Pre-drilling is only necessary if the material's limitations require a pilot hole to be drilled, as in hardwoods like Mahogany and Ipe'.
