S-90123A473 Length 7" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel material, ideal for harsh outdoor or marine wood applications.
• Enhanced torque transmission from the external hex drive and hex head design, ensuring secure fastening without stripping.
• Optimized thread engagement with a 1/2"-13 thread pitch and partial threading, reducing wood splitting while maintaining strong hold.
• High durability in wood due to thread forming tapping, which creates strong, permanent threads without pre-drilling in many cases.
• Reliable performance in demanding environments with a 7" length and 4.667" minimum thread length for deep, stable penetration.
• Compliance with industry standards including ASME B18.2.1, ensuring precise dimensions and consistent quality.
• Environmental and safety assurance through RoHS 3 and REACH compliance, supporting sustainable and safe manufacturing practices.

Professional Applications & Engineering Value

This 316 stainless steel hex head wood screw is engineered to address common challenges in wood construction, such as corrosion from moisture, chemical exposure, and high-stress loads. The thread forming design minimizes wood splitting by displacing material rather than cutting it, providing superior pull-out resistance in soft and hard woods. With its external hex drive and right-hand thread, it allows for efficient installation using standard tools, reducing assembly time in applications like decking, timber framing, and outdoor furniture. The partially threaded shank ensures that the unthreaded portion adds shear strength, while the pointed tip facilitates easy starting. Ideal for marine, agricultural, and industrial settings, this screw delivers long-term reliability and reduces maintenance costs.

Specification Summary & Compliance

This screw adheres to ASME B18.2.1 standards for dimensional accuracy, including a 1/2"-13 thread with a 0.5" diameter and 4.667" minimum thread length. It is manufactured in the inch system with a partially threaded, round shank and pointed tip for wood use. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets environmental and safety requirements for hazardous substance restrictions.
