DIN 7997:2016 Countersunk Head Phillips Wood Screw

DIN 7997:2016 Countersunk Head Phillips Wood Screw adopts a Phillips countersunk head and wood screw thread to meet the needs of wood and board joints needing a flush surface and efficient installation.

The Phillips recess suits power-driver operation, the countersunk head seats into the wood surface, and the thread profile increases holding in wood fibers. Its advantages lie in a clear installation method, well-defined load path, and good adaptability across different materials and installation spaces.

This product is suitable for furniture frames, timber panels, decorative boards, door and window components, and interior fittings. Zinc plating, stainless steel, brass, or colored head finishes can be adjusted for the final application, balancing cost control, corrosion protection, and assembly consistency.
