S-90031A567 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in demanding wood applications
• Enhanced driving efficiency with Phillips No. 2 drive that prevents cam-out and ensures secure installation
• Optimal flush mounting thanks to standard 82° flat head design that sits perfectly countersunk in wood surfaces
• Maximum thread retention through thread forming technology that creates stronger, more durable connections in wood
• Precision installation guidance with specific drill bit sizing for both hardwood (3/32") and softwood (5/64") applications
• Reduced splitting risk with partially threaded design that minimizes stress concentration in wood materials
• Reliable industrial compliance meeting RoHS 3 and REACH environmental standards for safe usage

Professional Applications & Engineering Value

These No. 8 wood screws are engineered to address common challenges in wood joining applications, particularly where vibration resistance and long-term structural integrity are critical. The black-oxide steel construction provides essential corrosion protection for interior woodworking projects, while the thread forming design creates permanent, high-strength connections without requiring pre-tapped holes. The Phillips flat head configuration ensures clean, flush finishes in furniture manufacturing, cabinetry, and construction applications. With specific drill bit recommendations for both hardwood and softwood materials, these screws eliminate guesswork and prevent material damage during installation. The 15 threads per inch configuration and 0.164" thread diameter deliver optimal holding power in various wood densities, making them ideal for professional woodworking and industrial assembly operations.

Specification Summary & Compliance

These wood screws feature precision inch system measurements with a No. 8 screw size, 1-1/2" length, and 0.164" thread diameter. The threading follows standard 15 threads per inch configuration with partial threading and right-hand direction. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industrial safety and substance restriction requirements. The flat head design incorporates an 82° countersink angle for proper seating in standard counterbored holes.
