S-92351A118 Length 8" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or outdoor wood applications
• Enhanced torque transmission through the external hex drive design, preventing cam-out and allowing for secure installation
• Maximum holding power achieved through thread forming technology, which compresses wood fibers rather than cutting them
• Optimized load distribution with partial threading design, reducing wood splitting while maintaining superior pull-out resistance
• Heavy-duty length and diameter (8" length with 5/16" diameter) providing exceptional grip depth for structural wood connections
• Industry-standard compatibility with standard hex tools and precise dimensional compliance for consistent performance
• Environmental compliance assurance meeting strict regulatory requirements for industrial use

Professional Applications & Engineering Value

Engineered for demanding wood construction applications, these 18-8 stainless steel hex head screws address critical challenges in structural fastening. The thread forming design creates stronger connections by compressing wood fibers rather than removing material, significantly reducing the risk of wood splitting while improving pull-out resistance by up to 30% compared to conventional wood screws. The external hex drive system ensures maximum torque transmission without stripping, making them ideal for heavy-duty framing, deck construction, and timber engineering where vibration resistance and long-term structural integrity are paramount. The partial threading configuration provides optimal stress distribution across the connection point, while the right-hand thread direction ensures standard installation compatibility across woodworking and construction industries.

Specification Summary & Compliance

These 5/16" x 8" wood screws feature precision Class 2A thread tolerances with 9 threads per inch and 4" minimum thread length. Manufactured in compliance with ASME B18.2.1 standards for dimensional accuracy and mechanical properties. The products are certified RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring environmental responsibility and workplace safety standards are met for industrial distribution and use.
