S-95452A155 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to the black oxide coating, extending service life in demanding woodworking environments
• Excellent torque transmission and slip resistance from the external hex drive design, ensuring secure installation with standard tools
• Reduced installation effort and material splitting with the pointed tip and thread-forming design for easier driving into wood
• Optimized clamping force and pull-out resistance through the partially threaded shank design for superior holding power
• Enhanced durability and structural integrity provided by the high-strength steel construction for heavy-duty applications
• Reliable dimensional consistency with compliance to ASME B18.2.1 standards, ensuring proper fit and performance
• Environmentally responsible manufacturing meeting RoHS 3 and REACH regulations for safe, compliant usage

Professional Applications & Engineering Value

These black oxide steel wood screws are engineered to address critical challenges in professional woodworking and construction. The thread-forming tapping method creates strong, permanent threads in wood substrates without pre-drilling in many applications, significantly reducing assembly time while preventing material cracking. The external hex drive provides superior torque transfer compared to Phillips or slotted drives, minimizing cam-out and tool slippage during high-torque installation in hardwoods or composite materials. With a substantial 4" length and 5/8" thread diameter, these partially threaded screws deliver exceptional pull-out resistance for structural connections, deck building, furniture assembly, and timber framing applications where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

These wood screws feature 5/8" diameter with approximately 5 threads per inch in right-hand direction, 2 1/2" minimum thread length, and partial threading configuration. Manufacturing complies with ASME B18.2.1 dimensional standards for consistent quality and performance. The products are fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making them suitable for professional and commercial applications with environmental compliance requirements.
