S-90031A589 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with Black-Oxide Steel coating for reliable performance in various woodworking environments.
• Superior holding power through thread forming technology that creates strong, permanent threads in wood without pre-tapping.
• Optimized for both hardwood and softwood with specific drill bit size recommendations (1/8" for hardwood, 7/64" for softwood) for perfect fit and maximum grip.
• Clean, flush installation with standard flat head profile and 82° countersink angle that sits perfectly flush with wood surfaces.
• Efficient driving and reduced cam-out with Phillips No. 2 drive that provides secure tool engagement during installation.
• Partial threading design allows for faster installation while maintaining excellent pull-out resistance in wood applications.
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe, sustainable manufacturing practices.

Professional Applications & Engineering Value

These No. 12 wood screws are engineered specifically for demanding wood applications where superior holding power and long-term reliability are critical. The Black-Oxide Steel construction provides essential corrosion protection, while the thread forming technology eliminates the need for separate tapping operations - the screws create their own perfectly matched threads in wood substrates. This design prevents stripping and ensures maximum thread engagement, particularly valuable in hardwood and softwood applications where material density varies. The Phillips flat head design with 82° countersink angle ensures professional, flush finishes in furniture manufacturing, cabinetry, and structural wood assemblies. The partially threaded configuration allows the unthreaded shank to act as a precision pilot, guiding the screw straight while the threaded portion delivers exceptional pull-out resistance.

Specification Summary & Compliance

These wood screws feature precision 0.216" thread diameter with 11 threads per inch and right-hand threading following standard inch measurements. The 2-1/2" length provides substantial penetration depth with 1.667" minimum thread length for secure fastening. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions and chemical safety in industrial applications.
