Simpson Strong-Tie Trim-Head Decking Screws are built for wood decking projects in high-exposure or marine environments where corrosion resistance matters most. Made from stainless steel, these screws feature a trim head with nibs that countersinks easily for a flush, professional finish that enhances the look of wood surfaces. Their clean design makes them a reliable choice for decks where appearance and durability are equally important.

Available in collated sharp-point stainless versions, that is compatible with Quik Drive® auto-feed systems, as well as 6-lobe and square-drive bulk options for hand-driving, Trim-Head screws deliver flexibility across different installation methods. Coarse threading ensures strong holding power, while curved collation provides smooth, efficient feeding during large decking projects.
