S-90031A586 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating, extending service life in various wood environments
• Enhanced holding power through thread forming technology that displaces wood fibers without cutting, creating stronger connections
• Flush finishing capability with standard 82° flat head profile and precise countersink angle for professional-looking installations
• Optimized material-specific performance with recommended drill bit sizes for both hardwood (1/8") and softwood (7/64") applications
• Reduced cam-out and improved torque transfer with No. 2 Phillips drive design for efficient installation
• Versatile partial threading allowing unthreaded shank to pull materials tightly together while threaded portion provides secure fastening
• Right-hand threading compatibility with standard installation tools and procedures

Professional Applications & Engineering Value

These black-oxide steel wood screws deliver exceptional engineering value through their specialized thread forming technology that eliminates the need for pre-tapped holes in wood applications. The thread forming design compresses wood fibers rather than cutting them, resulting in significantly enhanced pull-out resistance and vibration resistance compared to conventional wood screws. The partially threaded configuration with 1" minimum thread length ensures maximum clamping force when joining wood components, while the pointed tip facilitates easier starting and alignment. The 82° countersink angle and flat head profile provide seamless flush mounting in furniture manufacturing, cabinetry, and construction projects. These industrial wood fasteners are particularly valuable in applications requiring repeated disassembly and reassembly, as the formed threads maintain their integrity through multiple installation cycles.

Specification Summary & Compliance

This No. 12 x 1-1/2" wood screw features precise inch system dimensions including 0.216" thread diameter with 11 threads per inch, 0.438" head diameter, and standard flat head profile. Manufactured to exacting standards for wood fastening applications, these screws comply with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) compliance requirements, ensuring environmental responsibility and workplace safety. The thread forming tapping method and right-hand thread direction follow industry-standard practices for wood screw applications.
