S-90610A590 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance in various environments
• Enhanced torque transmission and reduced cam-out thanks to the No. 3 square drive design
• Strong, permanent thread formation in wood materials without pre-tapping, ensuring secure fastening
• Optimized for both hardwood and softwood with specific drill bit size recommendations (9/64" for hardwood, 7/64" for softwood)
• Clean, flush installation with standard flat head profile and 82° countersink angle
• Reduced wood splitting risk through partial threading design along the 2-1/2" length
• Reliable dimensional consistency with 0.242" thread diameter and 10 threads per inch for precise fit

Professional Applications & Engineering Value

These No. 14 wood screws are engineered to address common fastening challenges in woodworking and construction applications. The zinc-plated steel material provides essential corrosion protection for both interior and exterior projects, while the thread forming technology creates durable, permanent threads that eliminate the need for separate tapping operations. The square drive design delivers superior torque transmission compared to traditional drives, reducing tool slippage and improving installation efficiency. With specific drill size recommendations for both hardwood and softwood applications, these screws prevent material splitting and ensure optimal holding power. The partial threading design allows for effective clamping action while minimizing stress concentration, making them ideal for furniture assembly, cabinetry, deck building, and general carpentry where reliable, long-term fastening performance is critical.

Specification Summary & Compliance

These wood screws feature precise dimensional specifications including 0.242" thread diameter, 10 threads per inch, and 2-1/2" length with partial threading. The flat head design incorporates an 82° countersink angle for flush installation. Manufacturing complies with industry standards for thread forming screws and includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial usability.
