Professional Applications & Engineering Value

These No. 4 wood screws are engineered to address common challenges in woodworking and industrial assembly, where material integrity and fastener reliability are paramount. The 18-8 stainless steel composition provides excellent resistance to rust and corrosion, making these oval head slotted screws suitable for outdoor furniture, marine applications, and high-moisture environments. The thread forming design creates strong, permanent threads in wood without pre-tapping, minimizing stress cracks in both hardwood and softwood. With partial threading, the screw delivers superior clamping force while reducing the risk of wood splitting. The 82° countersink angle ensures a flush, professional finish that enhances both aesthetics and safety in finished products.
