S-92351A640 Length 4" 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 demanding environments
• Maximum torque transfer through external hex drive design, preventing tool slippage during installation
• Enhanced wood gripping power with thread-forming technology that creates strong, permanent threads in wood materials
• Optimized load distribution through partial threading design, reducing wood splitting while maintaining holding strength
• Quick and easy installation with pointed tip that self-starts in wood without pre-drilling in many applications
• Industry-standard compatibility with ASME B18.2.1 specifications ensuring reliable performance and interchangeability
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for safe, sustainable manufacturing

Professional Applications & Engineering Value

Engineered for demanding wood fastening applications, these 18-8 stainless steel hex head wood screws deliver exceptional performance in construction, furniture manufacturing, and industrial woodworking. The thread-forming design creates permanent, high-strength connections by displacing wood fibers rather than removing them, resulting in superior pull-out resistance. The external hex drive system provides maximum torque capability, making these screws ideal for heavy-duty applications where vibration resistance is critical. With partial threading and a pointed tip, installation is streamlined while minimizing wood splitting, even in hardwoods. These features combine to create reliable, long-lasting fastening solutions for outdoor structures, marine applications, and environments where moisture resistance is essential.

Specification Summary & Compliance

This 3/8"-7 x 4" wood screw features precision threading with approximately 7 threads per inch and a minimum thread length of 2-1/2".
