Professional Applications & Engineering Value

These No. 6 brass wood screws are engineered to address common challenges in woodworking, such as material splitting, corrosion, and inconsistent installation. The thread forming design with 18 TPI creates strong, permanent threads in wood without pre-tapping, significantly reducing the risk of cracks in delicate hardwoods or softwoods. The partial threading concentrates holding force near the head, preventing joint loosening under vibration or load. Combined with the oval head and 82° countersink, they ensure a seamless finish in furniture, cabinetry, and decorative wood projects. The corrosion-resistant brass material extends service life in moisture-prone environments, while the Phillips drive simplifies assembly with standard tools, enhancing productivity for professionals and DIY enthusiasts alike.

Specification Summary & Compliance
