S-91478A736 Length 6" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc plating that protects against rust in demanding wood applications
• Maximum torque transmission through external hex drive design for secure installation without stripping
• Enhanced holding power with thread forming technology that creates stronger, more permanent connections in wood
• Optimized wood penetration with pointed tip and partial threading for reduced splitting and easier driving
• Heavy-duty construction with 1/2" diameter and 6" length providing exceptional load-bearing capacity
• Industry-standard compatibility with 6 TPI coarse thread pattern ideal for wood construction applications
• Secure fastening performance with right-hand threading ensuring reliable, vibration-resistant connections

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve critical fastening challenges in industrial wood construction and structural applications. The zinc-plated steel construction provides essential corrosion protection for both indoor and outdoor environments, while the external hex drive delivers superior torque transmission that prevents cam-out during high-torque installation. The thread forming design creates stronger connections by compressing wood fibers rather than removing material, resulting in up to 30% greater pull-out resistance compared to conventional wood screws. With partial threading and pointed tip geometry, these screws reduce wood splitting while ensuring precise placement in demanding applications including timber framing, deck construction, and structural wood assemblies where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to exacting ASME B18.2.1 dimensional standards with Class 2A thread tolerances ensuring consistent performance and interchangeability. These 1/2" diameter wood screws feature 6 threads per inch coarse threading optimized for wood applications, with minimum thread length of 3-1/2" and overall length of 6". Fully compliant with RoHS 3 (2015/863/EU) environmental directives and REACH (EC 1907/2006) regulations for hazardous substances, making them suitable for regulated industrial and commercial applications worldwide.
