S-95452A149 Length 8" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from black oxide steel coating, extending service life in demanding wood applications
• Superior torque transmission through external hex drive design, preventing cam-out during high-torque installation
• Optimized thread engagement with 4-1/2" minimum thread length for maximum holding power in heavy timber
• Reduced splitting risk through thread forming design that displaces rather than removes wood material
• Quick alignment and driving with pointed tip and partial threading for faster installation in wood construction
• Industry-standard compatibility with 3/4" head width matching standard wrench sizes for consistent tooling
• Reliable performance assurance through compliance with ASME B18.2.1 manufacturing specifications

Professional Applications & Engineering Value

Engineered for heavy-duty wood construction and industrial timber applications, these 1/2"-6 partially threaded wood screws address critical challenges in structural wood fastening. The black oxide steel construction provides essential corrosion protection for both interior and exterior applications, while the thread forming design creates stronger, more secure connections by compressing wood fibers rather than cutting them. This approach significantly reduces material weakening and splitting in hardwoods and engineered lumber. The external hex drive ensures reliable torque transmission during installation, preventing stripping common in high-stress applications. With 8" length and substantial thread engagement, these screws deliver exceptional pull-out resistance for timber framing, deck construction, and heavy wood structural assemblies where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 dimensional standards with Class 2A thread tolerances, ensuring precise fit and consistent performance. The 1/2"-6 thread pitch and right-hand threading follow industry-standard patterns for compatibility with existing systems. Compliant with RoHS 3 (2015/863/EU) for hazardous substance restrictions and REACH (EC 1907/2006) regulations regarding chemical safety. The thread forming tapping method and partial threading design meet specialized requirements for wood fastening applications where material integrity and holding strength are critical performance factors.
