S-90123A242 Length 3" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor wood applications
• Enhanced driving efficiency through external hex head design providing maximum torque transfer and reduced cam-out
• Exceptional holding power achieved through thread forming technology that creates stronger engagement in wood materials
• Optimized thread engagement with partial threading that concentrates holding strength where needed most
• Reliable performance ensured by ASME B18.2.1 compliance for dimensional accuracy and interchangeability
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Versatile installation with pointed tip design for easier starting and reduced splitting in wood materials

Professional Applications & Engineering Value

These 316 stainless steel wood screws deliver exceptional performance in demanding wood fastening applications where corrosion resistance is critical. The thread forming design creates permanent, high-strength connections by displacing wood fibers rather than removing them, resulting in superior pull-out resistance compared to conventional wood screws. The external hex drive allows for high-torque installation, making these industrial wood screws ideal for structural applications, marine environments, and outdoor construction where exposure to moisture, chemicals, or salt spray would compromise ordinary fasteners. The combination of partial threading and precise 5/16" diameter ensures optimal stress distribution while the 3" length provides ample engagement for substantial wood members in decking, framing, and heavy timber construction.

Specification Summary & Compliance

This 5/16" x 3" wood screw features inch system measurements with right-hand threading and approximately 9 threads per inch. The screw maintains dimensional compliance with ASME B18.2.1 standards for consistent performance and interchangeability. Manufacturing and material composition adhere to RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance compliance. The 316 stainless steel composition provides excellent corrosion resistance, while the thread forming tapping method and partial threading design deliver reliable performance in wood applications.
