S-95452A147 Length 5 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black oxide steel coating for extended service life in demanding wood applications
• Superior torque transmission through the external hex head design, preventing cam-out during high-torque installation
• Exceptional holding power achieved through thread-forming technology that creates strong, permanent threads in wood
• Optimized load distribution with 3/4" head width providing wider bearing surface to prevent material pull-through
• Reduced splitting risk with partially threaded shank design that minimizes stress concentration in wood fibers
• Quick installation efficiency with pointed tip and 6 threads per inch configuration for faster driving in dense wood materials
• Reliable dimensional consistency ensuring proper fit and performance across all screws in your project

Professional Applications & Engineering Value

These black oxide steel hex head wood screws are engineered specifically for heavy-duty wood construction applications where structural integrity is paramount. The thread-forming tapping method creates compressed wood fibers around the threads, resulting in significantly higher pull-out resistance compared to conventional wood screws. This makes them ideal for timber framing, deck construction, and structural wood assemblies where vibration resistance and long-term stability are critical. The external hex drive style combined with the substantial 3/4" head width provides exceptional torque capability, allowing professionals to achieve proper clamping force without stripping the drive. The black oxide surface treatment offers reliable corrosion protection in both interior and protected exterior environments, while the partially threaded design ensures maximum holding strength by allowing the unthreaded shank to act as a dowel in the top material layer.

Specification Summary & Compliance

These wood screws feature standard inch measurements with a 1/2" thread diameter and 5-1/2" overall length, providing 3-1/4" of minimum thread engagement. Manufactured to ASME B18.2.1 dimensional standards for consistent performance and interchangeability. Fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations regarding chemical safety. The 6 threads per inch configuration follows industry standards for coarse-thread wood screws, optimized for maximum holding power in various wood densities.
