S-92185A341 5/16"-18 x 6" Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction and passivated finish
• High-strength performance with 70,000 PSI tensile strength and Rockwell B70 hardness for demanding applications
• Precise and reliable assembly ensured by the Class 3A thread fit for superior engagement and vibration resistance
• Secure and flush installation enabled by the standard socket head and hex drive design
• Optimized for specific fixturing with a partially threaded 6-inch rod and coarse UNC thread for faster installation
• Compliance with major environmental regulations, including RoHS 3 and REACH, for global supply chain integration
• Durable, long-lasting connection that withstands stress and exposure, reducing maintenance and replacement frequency

Professional Applications & Engineering Value

This 316 Stainless Steel Socket Head Cap Screw is engineered to solve critical challenges in industrial applications where corrosion and mechanical stress are primary concerns. The combination of 316 stainless steel and a passivated finish provides an exceptional barrier against chemicals, saltwater, and other corrosive agents, making it ideal for marine equipment, chemical processing plants, and food machinery. The UNC coarse thread and Class 3A thread fit ensure a precise, secure fit that resists loosening under vibration, a common failure point in dynamic systems. The hex drive and socket head allow for high-torque installation in confined spaces, enabling reliable fastening in complex assemblies. This screw delivers engineering value by enhancing equipment longevity, reducing downtime, and ensuring compliance with stringent industry standards.

Specification Summary & Compliance

This socket head cap screw adheres to precise dimensional standards, including a Class 3A thread fit for high-precision assemblies and UNC (Unified Coarse) thread form. The manufacturing ensures consistent thread diameter of 0.3125" and a minimum thread length of 1 1/8" on the partially threaded design. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in regulated markets and environmentally conscious projects.
