S-92351A819 Length 4" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for humid or outdoor wood applications
• Maximum torque transmission through external hex drive design, preventing cam-out during high-torque installation
• Enhanced pull-out strength with thread-forming tapping method that creates strong, permanent threads in wood
• Optimized thread engagement with 5 threads per inch and 2.667" minimum thread length for secure fastening in thick materials
• Easy alignment and installation with pointed tip and partial threading for precise positioning in wood projects
• Heavy-duty construction with 0.625" diameter and 4" length, capable of handling demanding structural applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe, sustainable manufacturing

Professional Applications & Engineering Value

These 18-8 stainless steel hex head wood screws deliver exceptional performance in demanding wood fastening applications where corrosion resistance and structural integrity are paramount. The thread-forming design eliminates the need for pre-tapping in hardwoods and engineered wood products, reducing installation time while creating stronger, more durable connections. The external hex drive system provides superior torque transmission compared to Phillips or slotted drives, preventing stripping during high-torque applications in industrial settings. With their partial threading and pointed tip, these screws facilitate precise alignment and prevent wood splitting, making them ideal for structural timber construction, outdoor decking, marine applications, and heavy-duty furniture assembly where moisture exposure and long-term reliability are critical concerns.

Specification Summary & Compliance

Manufactured to ASME B18.2.1 specifications with standard inch measurements, these wood screws feature a 5/8" diameter, 4" length, and 5 threads per inch configuration. The 18-8 stainless steel material provides excellent mechanical properties while the external hex head (0.938" width, 0.422" height) ensures reliable drive engagement. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards guarantees these fasteners meet current regulatory requirements for hazardous substances, making them suitable for global industrial applications requiring certified components.
