• Pointed tip design facilitates accurate positioning and easy starting in composite wood materials

Professional Applications & Engineering Value

These black-oxide steel wood screws are engineered specifically for fiberboard and particleboard applications where traditional fasteners often fail. The thread-forming tapping method eliminates the need for separate tapping operations while creating stronger thread engagement in composite wood materials. The partial threading design concentrates holding power where needed most, preventing material splitting in delicate wood composites. With 11 threads per inch and precise Class 2A thread tolerances, these Phillips pan head screws deliver consistent performance in production environments, reducing installation time and improving joint integrity in furniture manufacturing, cabinetry, and construction applications where reliable wood-to-wood fastening is critical.

Specification Summary & Compliance

Manufactured to standard inch system specifications with Class 2A thread tolerances and right-hand threading. These No. 8 wood screws feature a 0.164" thread diameter, 1.507" minimum thread length, and comply with industry-standard dimensional requirements for wood screw applications. The black-oxide surface treatment provides corrosion protection while maintaining compatibility with standard 5/64" drill bits for precise installation. Manufacturing processes adhere to quality standards suitable for professional woodworking and construction applications.
