S-95452A143 Length 3 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide steel coating for extended service life in demanding wood applications
• Enhanced driving torque capability through external hex head design preventing tool slippage during installation
• Maximum material displacement with thread forming technology creating permanent, vibration-resistant connections
• Optimized wood penetration with pointed tip and partial threading reducing installation effort while maintaining pull-out strength
• Industry-standard compatibility with 3/4" head width ensuring consistent performance across wrench sizes
• Reduced splitting risk through controlled thread pitch (6 TPI) design distributing stress evenly in wood substrates
• Regulatory compliance assurance meeting ASME B18.2.1 specifications and international environmental standards

Professional Applications & Engineering Value

Engineered for heavy-duty wood construction applications, these black oxide steel screws deliver exceptional performance in timber framing, structural wood assemblies, and industrial woodworking. The thread forming design eliminates the need for pre-drilling in many applications by displacing wood fibers rather than cutting them, creating superior holding power that resists vibration loosening. The external hex drive system provides maximum torque transmission for high-strength connections, while the partial threading configuration ensures optimal clamp force distribution. These industrial wood screws are particularly valuable in outdoor structures, pallet manufacturing, and architectural wood elements where corrosion resistance and long-term reliability are critical engineering considerations.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread tolerances. Features include: 1/2" thread diameter, 6 threads per inch, 3-1/2" overall length, and 2-1/4" minimum thread engagement. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The black oxide surface treatment provides consistent corrosion protection while maintaining dimensional accuracy for reliable performance in wood fastening applications.
