S-90031A580 Length 2 1/2" Wood Screws

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance: Black-oxide steel finish provides durable protection against rust, extending screw life in various woodworking environments.
• Superior Holding Power: Thread forming design creates strong, permanent threads in wood without pre-tapping, reducing the risk of pull-out and ensuring secure fastening.
• Efficient Installation: Phillips No. 2 drive offers reliable torque transfer and reduced cam-out, speeding up assembly while minimizing driver slippage.
• Clean, Flush Finishes: Standard flat head with 82° countersink angle sits seamlessly in wood surfaces, providing a smooth, professional appearance.
• Optimized Material Compatibility: Specified drill bit sizes (7/64" for hardwood, 3/32" for softwood) ensure precise pilot holes, preventing wood splitting and ensuring consistent performance.
• Versatile Fastening Length: 2-1/2" length with partial threading allows for controlled engagement and strong clamping force in a wide range of wood thicknesses.
• Regulatory Compliance: Meets RoHS 3 and REACH standards, ensuring safe, environmentally responsible use in professional and industrial applications.

Professional Applications & Engineering Value

These No. 10 wood screws are engineered to address common wood fastening challenges, such as material splitting and weak grip. The black-oxide steel construction resists corrosion, making them ideal for indoor and protected outdoor woodworking projects. With thread forming technology, the screws displace wood fibers to create tight, permanent threads, eliminating the need for separate tapping and enhancing pull-out resistance in both hardwood and softwood. The Phillips flat head design, combined with a standardized 82° countersink, ensures a flush finish that improves aesthetics and safety. These features make the screws highly reliable for furniture assembly, cabinetry, framing, and construction applications where durability and precision are critical.

Specification Summary & Compliance

This screw adheres to inch system measurements with a thread diameter of 0.19" and approximately 13 threads per inch, providing consistent engagement. The partially threaded shank and right-hand thread direction facilitate easy driving and secure fastening. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring the absence of hazardous substances and supporting environmental safety in industrial use.
