S-92351A121 Length 12" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in humid or outdoor wood applications.
• High-torque installation capability via the external hex drive, preventing cam-out and ensuring secure, efficient fastening.
• Enhanced holding power from the thread forming design, which creates strong, permanent threads in wood without pre-drilling in many cases.
• Deep penetration and grip due to the 12" length and 4" minimum thread length, ideal for thick wood members and structural connections.
• Reliable dimensional consistency meeting ASME B18.2.1 specifications, ensuring interchangeability and predictable performance.
• Reduced risk of splitting with a partially threaded shank, allowing the unthreaded portion to act as a dowel for added stability.
• Environmental and safety compliance with RoHS 3 and REACH regulations, making them suitable for regulated industrial and construction projects.

Professional Applications & Engineering Value

These 3/8" x 12" wood screws are engineered to address common challenges in heavy-duty wood construction, such as joint failure under load and corrosion in exposed environments. The 18-8 stainless steel material provides excellent resistance to rust and oxidation, critical for outdoor decks, marine structures, or treated lumber applications. The external hex drive allows for high torque application with standard tools, minimizing slippage and ensuring tight, reliable connections in framing, timber engineering, and industrial wood assemblies. The thread forming design displaces wood fibers to create a tight, vibration-resistant fit, reducing the need for additional adhesives or inserts. With a 12" length and right-hand thread, these screws offer deep embedment for maximum withdrawal resistance, making them a trusted choice for architects and contractors seeking durable, code-compliant fastening solutions.

Specification Summary & Compliance

This product adheres to ASME B18.2.1 dimensional and mechanical standards, ensuring precise thread fit (approximately 7 threads per inch) and consistent Class 2A thread tolerances for reliable assembly. The screws feature a 0.375" diameter, partial threading, and a pointed tip for easy starting. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) confirms the absence of hazardous substances, supporting use in environmentally sensitive and regulated industrial projects.
