S-95452A124 Length 5 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black oxide coating that protects against rust in demanding wood applications
• Maximum torque transmission through external hex drive design, preventing cam-out during high-torque installation
• Enhanced holding power with partial threading that concentrates gripping force where it matters most
• Reduced splitting risk thanks to thread forming technology that displaces material rather than removing it
• Quick and easy installation with pointed tip design that eliminates the need for pre-drilling in many applications
• Industry-standard compatibility with 1/2" head width and 9 threads per inch for universal tool matching
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, regulated manufacturing

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered to solve critical fastening challenges in construction and woodworking applications. The black oxide steel construction provides essential corrosion protection for both indoor and outdoor projects, while the thread forming design eliminates wood splitting by compressing fibers rather than cutting them. The external hex drive ensures maximum torque transmission for demanding structural connections, and the partial threading concentrates holding power while reducing installation resistance. At 5 1/2" length with 3 1/4" minimum thread engagement, these ASME B18.2.1 certified screws deliver reliable performance in timber framing, deck construction, furniture manufacturing, and other professional wood applications where failure is not an option.

Specification Summary & Compliance

This 5/16" x 5 1/2" wood screw features Class 2A thread tolerances with right-hand threading and 9 threads per inch. Manufactured to ASME B18.2.1 specifications for dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial applications. The combination of inch system measurements, standardized head dimensions (1/2" width, 0.219" height), and controlled partial threading provides consistent, predictable performance in professional wood fastening scenarios.
