S-94048A224 Length 2 1/2" ASME B18.2.1, ASTM A307, SAE J429 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with hot-dipped galvanized steel coating for long-lasting performance in humid or outdoor wood applications
• Maximum torque transfer and slip resistance through external hex drive design, allowing for high-tightening force without stripping
• Enhanced pull-out resistance in wood due to thread-forming design that creates strong, permanent threads without pre-drilling in many cases
• Optimized thread engagement with 10 TPI and 1.667" minimum thread length for secure fastening in various wood densities
• Reduced wood splitting through partially threaded shank design that minimizes stress concentration
• Reliable mechanical properties meeting ASTM A307 and SAE J429 grade requirements for consistent strength and durability
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

These hot-dipped galvanized steel hex head wood screws deliver exceptional value in demanding wood fastening applications where corrosion resistance and structural integrity are paramount. The thread-forming design creates permanent mating threads in wood substrates, eliminating the need for tapping operations while providing superior resistance to vibration loosening. The external hex drive configuration enables high torque application during installation, making these screws ideal for heavy-duty construction, timber framing, and outdoor wood structures where weather exposure demands the protective galvanized coating. The partially threaded configuration with pointed tip facilitates easier starting and reduces the risk of wood splitting, while the specified 1/4" diameter and 2-1/2" length provide optimal strength-to-size ratio for substantial wood members.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread tolerances, these wood screws ensure precise fit and reliable performance. The 10 threads per inch configuration follows unified thread standards for consistent engagement. Material compliance includes ASTM A307 for mechanical properties and SAE J429 for quality assurance. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, confirming absence of restricted substances for industrial use.
