S-90123A642 Length 5" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction
• Maximum torque transmission and reduced cam-out with the external hex drive design
• Exceptional holding power in wood achieved through the thread-forming tapping method
• Optimized for high-strength applications with a substantial 5" length and 3/4" diameter
• Enhanced assembly control from the partially threaded shank, preventing material splitting
• Guaranteed dimensional reliability and interchangeability through ASME B18.2.1 compliance
• Safe for regulated industries with full RoHS 3 and REACH environmental compliance

Professional Applications & Engineering Value

This 316 stainless steel hex head wood screw is engineered to solve critical challenges in demanding wood applications, from marine construction to outdoor industrial fixtures. The external hex drive ensures high torque can be applied without stripping the head, a common failure point in softer materials. Its thread-forming design displaces wood fibers to create a tighter, more secure fit with superior pull-out resistance compared to thread-cutting alternatives. The combination of a 0.75" diameter and 5" length provides a robust clamping force over a large area, making it ideal for heavy timber framing, decking, and structural wood connections where vibration and load stress are significant concerns. The partial threading allows the unthreaded shank to act as a precise shoulder, ensuring components are drawn together tightly without compromising the material's integrity.

Specification Summary & Compliance

This screw features a 3/4" diameter with approximately 4.5 threads per inch and a right-hand thread. It is partially threaded with a minimum thread length of 3.333" and an overall length of 5". The product is manufactured to conform to the dimensional standards of ASME B18.2.1. It is also verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets strict environmental and safety regulations for industrial use.
