Professional Applications & Engineering Value

These No. 7 wood screws with Black-Oxide Steel construction and thread forming technology address critical challenges in wood assembly applications. The Phillips flat head design ensures flush mounting while the specialized threading creates permanent, high-strength connections that resist loosening under vibration and load stress. The partially threaded configuration concentrates holding power where needed most, preventing wood splitting while maintaining structural integrity. Ideal for furniture manufacturing, cabinetry, and wood framing, these screws provide reliable performance in both hardwood and softwood applications with their optimized drill bit specifications, ensuring proper fit and maximum pull-out resistance for professional-grade results.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.151" thread diameter and 16 threads per inch configuration. Features right-hand threading and standard flat head profile with 82° countersink angle for proper seating. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial suitability. The thread forming tapping method eliminates the need for separate tapping operations, streamlining installation processes while maintaining thread integrity.
