S-91478A587 Length 1 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in humid or outdoor wood applications
• Enhanced driving efficiency through external hex head design, allowing high torque application without cam-out
• Optimized thread engagement with 9 TPI thread forming design, creating strong permanent threads in wood substrates
• Reduced material splitting with partial threading and pointed tip for controlled penetration in dense woods
• Reliable dimensional consistency meeting ASME B18.2.1 specifications for precise fit and predictable performance
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe industrial and construction use
• Versatile application capability with 1-1/2" length providing substantial holding power for various wood thicknesses

Professional Applications & Engineering Value

These 5/16" zinc-plated steel wood screws deliver exceptional engineering value through their thread forming design that eliminates the need for pre-drilling in many wood applications. The external hex drive system provides superior torque transmission, preventing stripping during high-stress installations in construction frameworks, furniture manufacturing, and outdoor wood structures. The partial threading configuration concentrates holding power where needed most while minimizing wood splitting risks. The zinc plating offers critical corrosion protection, making these industrial wood screws suitable for interior and exterior applications where moisture resistance is essential. With their 1-1/2" length and 9 TPI thread pitch, they provide optimal pull-out resistance in both soft and hard woods, addressing common fastening challenges in wood-to-wood connections.

Specification Summary & Compliance

These wood screws feature inch system measurements with 5/16" thread diameter and 1-1/2" length, manufactured to ASME B18.2.1 dimensional standards for consistent quality. The thread forming tapping method and right-hand thread direction ensure reliable installation performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental safety and restricted substance adherence, making them suitable for regulated industrial markets and sustainable construction projects.
