S-95452A156 Length 4 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 that prevents stripping during high-torque installation
• Enhanced holding power with thread forming technology that compresses wood fibers for stronger, more secure connections
• Optimized wood penetration featuring pointed tip and partial threading that reduces splitting while maintaining superior pull-out resistance
• Heavy-duty construction with 5/8" diameter and 4-1/2" length designed for structural wood applications requiring exceptional strength
• Reliable installation performance with 5 TPI coarse thread pattern that ensures fast, secure fastening in various wood types
• Industry-standard compatibility meeting ASME B18.2.1 specifications for consistent quality and dimensional accuracy

Professional Applications & Engineering Value

These heavy-duty wood screws are engineered specifically for demanding construction and timber applications where failure is not an option. The black oxide steel construction provides essential corrosion protection for outdoor structures, decking, and timber framing exposed to environmental elements. The thread forming design eliminates the need for pre-drilling in many applications by displacing wood fibers rather than removing them, creating compressed material around the threads that significantly increases pull-out resistance. The external hex drive system ensures maximum torque transmission for secure installations without cam-out, while the partial threading configuration provides superior clamping force by allowing unthreaded shank sections to act as dowels within the material. These 5/8" diameter screws with coarse 5 TPI threading are particularly effective in softwoods, engineered lumber, and composite wood products where traditional fasteners may struggle with holding power.

Specification Summary & Compliance

These wood screws feature precision 5/8" diameter threads with approximately 5 threads per inch and 2-3/4" minimum thread length following standard inch measurements. The manufacturing process adheres to ASME B18.2.1 dimensional standards ensuring consistent quality and interchangeability. The products are fully RoHS 3 (2015/863/EU) compliant and meet REACH (EC 1907/2006) compliance requirements regarding substance restrictions, making them suitable for various international markets and environmental regulations.
