• Clean, flush finishing achieved through standard flat head profile with 82° countersink angle
• Reliable dimensional consistency with precise No. 5 diameter and 20 threads per inch for predictable performance

Professional Applications & Engineering Value

These zinc-plated steel wood screws are engineered to address common fastening challenges in woodworking and construction applications. The thread forming technology eliminates the need for pre-tapped holes while creating stronger thread engagement than conventional cutting threads, significantly reducing the risk of pull-out in both hardwood and softwood materials. The partial threading design concentrates the screw's holding power in the engagement zone while minimizing stress concentration in the shank area, preventing material splitting. The Phillips flat head configuration ensures flush installation with standard 82° countersinks, providing clean aesthetic finishes in furniture manufacturing, cabinetry, and structural wood assemblies. The combination of zinc plating corrosion protection and precise dimensional control makes these screws ideal for both interior and protected exterior applications where reliability and appearance matter.
