The GRK FIN/Trim Head Screws are designed for fine carpentry and precision trim work, making them ideal for window extension jambs, molding, and other detailed wood installations. Perfect for composite decks and trim applications, these screws combine strength, speed, and a clean finished appearance. Engineered with W-Cut threads and Zip-Tip points, they minimize wood splitting and allow for fast, single-step installation without pre-drilling. The Climatek indoor/outdoor coating provides corrosion resistance and is approved for use in treated lumber under ICC-ES AC257. The trim head design ensures a neat, professional look, while the precision recessed star drive offers six points of contact to eliminate stripping.
