S-92351A857 Length 12" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in humid or outdoor wood applications.
• Maximum torque transmission via the external hex drive and hex head design, preventing cam-out and enabling quick, secure installations.
• Enhanced holding power through the thread forming tapping method, which compresses wood fibers for a tight, vibration-resistant grip.
• Optimized for heavy-duty wood fastening with a 12" length and 5/8" diameter, providing deep penetration and robust structural support.
• Efficient installation with a pointed tip and right-hand threading, allowing for smooth driving and reduced splitting in wood.
• Reliable partial threading that ensures strong clamping force while minimizing thread exposure in non-critical sections.
• Compliance with industry standards including ASME B18.2.1, RoHS 3, and REACH, guaranteeing safety and environmental responsibility.

Professional Applications & Engineering Value

Engineered for demanding wood fastening applications, this 18-8 stainless steel hex head wood screw addresses common industrial challenges such as material degradation and joint failure. The thread forming design eliminates the need for pre-drilling in many scenarios, reducing labor time while creating strong, permanent threads in wood that resist loosening under dynamic loads. Its corrosion-resistant properties make it ideal for outdoor structures, marine environments, and high-moisture settings where ordinary fasteners would fail. The external hex drive ensures high torque capability, preventing strip-outs during installation in dense hardwoods or composite lumber. By combining precise 5 TPI threading with a partially threaded shank, it delivers superior pull-out strength and clamping force, essential for timber construction, decking, and furniture manufacturing where long-term integrity is critical.

Specification Summary & Compliance

This screw adheres to ASME B18.2.1 dimensional and mechanical standards, ensuring consistent quality and interchangeability. The thread diameter of 0.625" (5/8") and 5 threads per inch provide optimal engagement in wood, while the minimum thread length of 4" guarantees sufficient gripping area. It is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming the absence of hazardous substances and supporting sustainable procurement practices for industrial and commercial projects.
