S-91478A732 Length 5" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for long-lasting performance 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 creates stronger, more secure connections in wood materials
• Optimized thread engagement featuring 6 threads per inch and partial threading for balanced grip strength and installation efficiency
• Heavy-duty structural capability with substantial 5" length and 1/2" diameter for demanding wood construction projects
• Reliable industrial performance backed by ASME B18.2.1 compliance ensuring consistent quality and dimensional accuracy
• Environmentally responsible manufacturing meeting RoHS 3 and REACH standards for sustainable procurement

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 external hex drive delivers superior torque transmission capability - eliminating cam-out issues common in high-tension installations. The thread forming design creates stronger connections by compressing wood fibers rather than removing them, resulting in up to 30% greater pull-out resistance compared to conventional wood screws. With 1/2" diameter and 5" length, these partially threaded screws offer optimal clamping force distribution for structural wood assemblies, timber framing, and heavy-duty furniture manufacturing where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 standards ensuring dimensional precision and consistent performance. Features right-hand thread direction with 6 threads per inch and Class 2A thread fit for reliable engagement. The partially threaded design provides 3" minimum thread length for optimal grip strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for regulated industries and sustainable procurement programs.
