S-92351A559 Length 4 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in humid or outdoor wood applications
• Enhanced torque transmission through the external hex head design, preventing cam-out and ensuring secure fastening
• Optimized wood gripping power with thread forming technology that creates stronger, more durable connections without pre-drilling
• Reduced material splitting thanks to the partially threaded shank design that minimizes stress concentration in wood
• Quick and easy installation with pointed tip for precise starting position and right-hand threading for standard driving
• Heavy-duty performance with 4-1/2" length and 2-3/4" minimum thread engagement for substantial wood construction projects
• Industry-standard compatibility meeting ASME B18.2.1 specifications for reliable dimensional accuracy and performance

Professional Applications & Engineering Value

These 1/4"-10 partially threaded wood screws deliver exceptional engineering value for demanding wood construction applications. The 18-8 stainless steel material provides outstanding corrosion resistance, making them ideal for outdoor structures, marine environments, and high-moisture applications where rust prevention is critical. The thread forming tapping method creates stronger, more permanent connections in wood by displacing material rather than removing it, resulting in superior pull-out resistance. The partially threaded design with substantial 2-3/4" minimum thread length ensures maximum holding power while reducing the risk of wood splitting. The external hex drive system allows for high-torque installation without stripping, making these screws perfect for heavy timber construction, deck building, furniture manufacturing, and structural wood assemblies where reliability and durability are paramount.

Specification Summary & Compliance

This 1/4"-10 wood screw features precise dimensional accuracy compliant with ASME B18.2.1 standards, ensuring consistent performance and interchangeability. The screw maintains a 10 threads per inch pitch with right-hand threading and partial threading configuration. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) compliance for chemical safety, making these screws suitable for professional and regulated applications where environmental and safety standards are required.
