S-95452A123 Length 5" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating for long-lasting performance in humid or outdoor wood applications
• Enhanced driving torque capability through external hex head design that prevents cam-out and allows high-tightening force
• Reduced splitting and superior holding power with thread forming tapping method that compresses wood fibers rather than cutting them
• Optimized load distribution through partial threading that maintains maximum shank strength along the 5" length
• Precise 9 threads per inch configuration ensuring secure fastening in various wood densities without stripping
• Extended 3" minimum thread length providing deep penetration and exceptional pull-out resistance in demanding wood constructions
• Industry-standard compliance meeting ASME B18.2.1 specifications for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

These 5/16" x 5" Black Oxide Steel wood screws deliver exceptional engineering value for heavy-duty wood construction projects where failure is not an option. The thread forming design eliminates wood fiber removal, creating stronger threads by compressing material around the 0.313" diameter threads. This prevents splitting in hardwoods and composite materials while providing superior resistance to vibrational loosening. The external hex drive system ensures maximum torque transmission without stripping, critical for structural applications like timber framing, deck construction, and outdoor furniture. The black oxide finish provides an additional layer of corrosion protection, extending service life in environments exposed to moisture and temperature variations. With partial threading maintaining full shank diameter along most of the 5" length, these screws offer optimal shear strength for load-bearing connections.

Specification Summary & Compliance

These wood screws feature precision right-hand threads with 9 threads per inch and Class 2A thread tolerances per ASME B18.2.1 standards. The 5/16" diameter and 5" length provide consistent dimensional accuracy for reliable performance. Manufacturing complies with ASME B18.2.1 specifications for hex head cap screws, ensuring interchangeability and proper fit. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming the absence of restricted hazardous substances for safe industrial use.
