S-91478A595 Length 3" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding wood applications
• Maximum torque transfer through external hex drive design, preventing tool slippage during installation
• Enhanced holding power with thread forming tapping method that creates stronger mating threads in wood substrates
• Optimized thread engagement with 9 threads per inch configuration for secure fastening in various wood densities
• Versatile partial threading allowing unthreaded shank section to act as a built-in washer for improved clamping force
• Industry-standard compliance meeting ASME B18.2.1 specifications for dimensional accuracy and performance reliability
• Environmental responsibility through RoHS 3 and REACH compliance for safe industrial usage

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve common fastening challenges in wood construction and manufacturing. The zinc-plated steel material provides essential corrosion protection for both indoor and outdoor applications, while the external hex drive delivers exceptional torque transmission for high-tension assemblies. The thread forming design eliminates the need for pre-tapped holes, creating permanent, vibration-resistant connections in solid wood, engineered lumber, and composite wood products. With partial threading and pointed tip, these screws facilitate precise positioning and prevent material splitting, making them ideal for structural framing, furniture manufacturing, deck construction, and pallet assembly where maximum holding power and long-term reliability are critical.

Specification Summary & Compliance

These wood screws feature precise dimensional specifications including 5/16" thread diameter, 3" length with 2" minimum thread length, and 9 threads per inch configuration. Manufacturing complies with ASME B18.2.1 standards for dimensional accuracy and mechanical properties. The products are fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring they meet current environmental and safety requirements for industrial distribution and use.
