S-95452A163 Length 2 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 torque transmission through external hex drive design, preventing cam-out during high-torque installation
• Optimal thread engagement with 4.5 TPI thread forming design that creates strong, permanent threads in wood materials
• Maximum holding power achieved through 1 3/4" minimum thread length for secure fastening in structural applications
• Easy alignment and installation with partially threaded shank design that reduces wood splitting
• Industry-standard compatibility with 1 1/8" hex head meeting ASME B18.2.1 specifications for reliable performance
• Environmental compliance assurance with RoHS 3 and REACH compliance for safe use in industrial settings

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to address critical challenges in industrial wood fastening applications where structural integrity and long-term reliability are paramount. The black oxide steel construction provides essential corrosion protection for outdoor structures, timber framing, and industrial wood assemblies exposed to environmental elements. The thread forming design with 4.5 TPI creates compressed wood fibers around the threads, resulting in superior pull-out resistance compared to conventional wood screws. The external hex drive system combined with the substantial 1 1/8" head width delivers exceptional torque transmission capability, preventing fastener failure during installation in dense hardwoods and engineered wood products. This combination of material strength, thread geometry, and drive efficiency makes these screws ideal for construction, pallet manufacturing, and heavy timber applications where vibration resistance and long-term structural stability are critical requirements.

Specification Summary & Compliance

These 3/4" wood screws feature precision thread forming technology with 4.5 threads per inch and right-hand threading configuration. The fasteners maintain dimensional accuracy per ASME B18.2.1 specifications, ensuring consistent performance and interchangeability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance management. The partially threaded design with pointed tip facilitates proper alignment and reduces installation stress on wood materials, while the 1 3/4" minimum thread length provides optimal engagement depth for maximum holding capacity in various wood densities.
