S-90000A297 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid or outdoor environments where rust prevention is critical
• Enhanced driving torque and reduced cam-out thanks to the square drive design, ensuring secure installation and minimizing tool slippage
• Self-tapping efficiency through thread cutting technology, eliminating the need for pre-drilled pilot holes in many wood and composite applications
• Optimal material engagement with a 0.216" thread diameter and 11 threads per inch, providing strong holding power in wood and plastic-wood composites
• Clean, flush installation with a standard flat head profile, creating a smooth surface finish for professional-looking projects
• Reliable partial threading design allows unthreaded shank to act as a built-in shear plane, increasing resistance to pull-out forces
• Environmental and safety compliance with RoHS 3 and REACH regulations, ensuring safe use in commercial and residential applications

Professional Applications & Engineering Value

These 316 stainless steel wood screws deliver exceptional performance in demanding wood and plastic-wood composite fastening applications. The thread cutting design creates precise mating threads during installation, eliminating the need for separate tapping operations and reducing assembly time. The square drive system provides superior torque transmission compared to traditional Phillips drives, preventing stripping during high-torque applications. With their partially threaded configuration, these screws offer enhanced resistance to vibration loosening while maintaining excellent pull-out strength. The combination of marine-grade 316 stainless steel and compliant surface treatment ensures long-term reliability in moisture-prone environments, making them ideal for outdoor furniture, decking, marine construction, and architectural woodworking where corrosion resistance and structural integrity are paramount.

Specification Summary & Compliance

These screws feature a No. 12 size with 2-1/2" length and standard inch system measurements. The threading follows industry standards with a 0.216" diameter and 11 threads per inch configuration. The flat head design incorporates a standard profile for flush mounting applications. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The thread cutting Type 17 point and square drive No. 3 size provide reliable performance in wood and plastic-wood composite materials without requiring pre-tapped holes.
