S-91478A628 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 demanding wood applications
• Maximum torque transmission through external hex drive design, preventing cam-out and ensuring secure installation
• Enhanced holding power with thread-forming design that creates stronger, more permanent connections in wood materials
• Optimized pull-out resistance through 1-1/4" minimum thread length and partial threading design
• Industry-standard compatibility with 7 threads per inch and 3/8" diameter meeting common wood fastening requirements
• Quick installation with pointed tip design that facilitates easier starting and reduced splitting in wood substrates
• Reliable performance backed by ASME B18.2.1 specifications for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to address common challenges in wood construction and industrial applications. The zinc-plated steel construction provides essential corrosion protection, while the external hex drive delivers superior torque transmission compared to standard screw heads, reducing installation time and preventing tool slippage. The thread-forming design creates permanent, high-strength connections by displacing wood fibers rather than removing them, resulting in up to 30% greater pull-out resistance than conventional threaded fasteners. With partial threading and precise 7 threads per inch configuration, these screws are ideal for structural wood applications, timber framing, deck construction, and industrial wood assemblies where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 standards with Class 2A thread tolerances, these 3/8" diameter wood screws feature right-hand threading and precise dimensional control. The products are fully compliant with RoHS 3 (2015/863/EU) regulations and REACH (EC 1907/2006) requirements, ensuring environmental responsibility and workplace safety. The zinc plating meets industry standards for corrosion protection, while the inch system measurements provide compatibility with North American wood construction specifications and tooling systems.
