Key Features & Benefits at a Glance

  • Enhanced corrosion resistance with zinc-plated steel construction for reliable performance in various woodworking environments
  • Superior holding power achieved through partial threading design that maximizes grip in wood materials
  • Optimized wood penetration with pointed tip and 10 threads per inch for smooth installation and reduced splitting
  • Flush finishing capability with standard 82° flat head profile that sits perfectly countersunk in wood surfaces
  • Material-specific drilling guidance with recommended bit sizes for both hardwood (9/64") and softwood (7/64") applications
  • Thread forming technology that creates strong, secure threads in wood without pre-tapping requirements
  • Industry compliance assurance meeting RoHS 3 and REACH regulations for safe industrial and commercial use

Professional Applications & Engineering Value

These No. 14 wood screws are engineered to address common challenges in wood fastening applications. The zinc-plated steel construction provides essential corrosion protection for both interior and exterior wood projects, while the flat head design with standard 82° countersink angle ensures flush mounting without protruding hardware. The partially threaded configuration delivers maximum holding power by allowing the unthreaded shank to pull materials tightly together, preventing joint separation. The thread forming technology creates precise mating threads in wood substrates, eliminating the need for separate tapping operations and reducing installation time. With specific drill bit recommendations for both hardwood and softwood applications, these screws minimize material splitting and ensure proper thread engagement across various wood densities commonly encountered in furniture manufacturing, cabinetry, and construction projects.

Specification Summary & Compliance

These wood screws feature a No. 14 screw size with 0.242" thread diameter and 10 threads per inch in right-hand direction. The partially threaded design provides 1.66" minimum thread length on a 2-1/2" overall length. Manufactured to precise dimensional standards with flat head profile and slotted drive style. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial and commercial applications.
