S-91478A712 Length 1 1/2" 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 humid or outdoor wood applications
• Maximum torque transmission through 3/4" hex head design prevents stripping during high-tension installations
• Enhanced wood holding power with thread forming design that compresses wood fibers rather than cutting them
• Optimized load distribution through partial threading that concentrates threads where maximum grip is needed
• Quick installation alignment with pointed tip design for accurate positioning in wood materials
• Reliable dimensional consistency meeting ASME B18.2.1 specifications for predictable performance
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe industrial use

Professional Applications & Engineering Value

This heavy-duty wood screw delivers exceptional engineering value for demanding wood fastening applications where structural integrity is paramount. The zinc-plated steel construction provides essential corrosion protection for outdoor structures, decking, and timber framing exposed to environmental elements. The external hex drive combined with the substantial 3/4" hex head enables high-torque installation without cam-out, crucial for industrial wood assembly where vibration resistance matters. The thread forming design creates stronger connections by compressing wood fibers rather than removing material, significantly reducing the risk of pull-out in softwoods and engineered lumber. With 1/2"-13 coarse threading and partial threading, this fastener optimizes clamping force distribution while minimizing wood splitting in critical structural joints.

Specification Summary & Compliance

This wood screw features precision 1/2"-13 UNC coarse threading with standard thread tolerances, 1-1/2" overall length with 1-1/4" minimum thread length, and right-hand thread direction. Manufacturing and dimensional compliance meets ASME B18.2.1 specifications for hex head screws. Environmental regulatory compliance includes RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) chemical safety standards, ensuring suitability for professional and industrial wood fastening applications.
