S-91478A607 Length 6" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding wood applications
• Maximum torque transmission through external hex drive design, preventing tool slippage during high-tension installations
• Enhanced holding power with thread forming technology that compacts wood fibers rather than cutting them
• Optimized thread engagement with 9 threads per inch and 3½" minimum thread length for superior pull-out resistance
• Easy alignment and penetration with pointed tip design that guides screws accurately into wood materials
• Reduced splitting risk with partially threaded shank that minimizes stress concentration in wood
• Industry-standard compatibility with 1/2" hex head dimensions for use with standard socket tools

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve critical fastening challenges in wood construction and industrial applications. The zinc-plated steel construction provides essential corrosion protection for both indoor and outdoor projects, while the thread forming design creates stronger connections by compressing wood fibers rather than removing material. This approach significantly increases pull-out resistance compared to conventional wood screws. The external hex drive system ensures maximum torque transmission for secure installations in hardwoods and engineered wood products. With a substantial 6" length and 5/16" diameter, these partially threaded screws offer exceptional holding power for structural applications, deck building, timber framing, and heavy furniture assembly where reliability is paramount.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with Class 2A thread tolerances, these wood screws feature right-hand threading with 9 threads per inch and a 0.313" thread diameter. The product meets RoHS 3 (2015/863/EU) compliance standards and is REACH (EC 1907/2006) compliant, ensuring environmental responsibility and safety for industrial use. The zinc-plated surface treatment provides consistent corrosion protection while maintaining dimensional accuracy throughout the 6" length.
