S-95452A131 Length 2 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating for extended service life in demanding wood applications
• Maximum torque transmission through external hex head design, preventing cam-out during high-torque installation
• Exceptional holding power achieved through thread-forming technology that creates permanent, secure connections in wood
• Reduced splitting risk with partially threaded shank design that minimizes stress concentration in wood materials
• Precision dimensional control meeting ASME B18.2.1 specifications for consistent performance and interchangeability
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe, sustainable manufacturing
• Optimized thread engagement with 7 threads per inch configuration providing balanced pull-out resistance and installation efficiency

Professional Applications & Engineering Value

These black oxide steel hex head wood screws deliver exceptional engineering value in demanding wood construction and fabrication applications. The thread-forming tapping method creates permanent, high-strength connections by displacing wood fibers rather than removing them, resulting in superior pull-out resistance compared to conventional cutting threads. The external hex drive system provides maximum torque transmission capability, making these screws ideal for structural wood assemblies, timber framing, and heavy-duty furniture manufacturing where vibration resistance and long-term reliability are critical. The partial threading design concentrates holding power where needed while minimizing the risk of wood splitting, particularly important when working with hardwoods and engineered wood products. These industrial-grade wood screws maintain dimensional precision throughout their 2-1/2" length, ensuring consistent performance in repetitive assembly operations.

Specification Summary & Compliance

Manufactured to exact ASME B18.2.1 dimensional standards with right-hand threading and 7 threads per inch configuration. The 3/8" diameter screw features a 1-3/4" minimum thread length on a 2-1/2" overall length with pointed tip for easy starting. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures these fasteners meet the latest industry requirements for hazardous substance restrictions and chemical safety.
