Professional Applications & Engineering Value

These No. 20 wood screws are engineered to solve common fastening challenges in woodworking and construction applications. The zinc-plated steel construction provides essential corrosion protection, while the thread forming design eliminates the need for pre-tapped holes, creating stronger threads that resist pull-out forces. The partial threading maintains the screw's tensile strength while concentrating threads where holding power matters most. The Phillips flat head with standard profile ensures flush installation in hardwood furniture, softwood framing, and various construction projects. With specific drill bit sizing for different wood densities (13/64" for hardwood, 11/64" for softwood), these screws deliver consistent performance and prevent wood splitting, making them ideal for professional woodworking, cabinetry, and structural applications where reliability is critical.
