S-92185A804 5/8"-11 x 2 1/2" Super-Corrosion-Resistant 316 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction and passivated finish
• Exceptional mechanical strength with 70,000 PSI tensile strength and Rockwell B70 hardness for reliable, high-stress load bearing
• Precise, secure fastening ensured by Class 3A thread fit and UNC coarse thread profile for reduced cross-threading risk
• Optimized torque transmission via the 1/2" hex drive and standard socket head profile, minimizing tool slippage
• Versatile partial threading design allows for both secure clamping and unthreaded shaft guidance in assemblies
• Regulatory compliance assurance with RoHS 3 and REACH standards, meeting international environmental and safety mandates
• Durable, long-lasting performance in chemical and marine applications due to the material's inherent pitting resistance

Professional Applications & Engineering Value

Engineered for demanding industrial environments, this 316 stainless steel socket head cap screw delivers critical reliability where corrosion resistance and mechanical integrity are paramount. The UNC coarse thread and Class 3A thread fit provide rapid assembly with high clamping force, reducing installation time while maintaining joint security. The passivated finish enhances the alloy's natural resistance to chlorides and acidic agents, making it ideal for chemical processing, marine equipment, and offshore applications. Its partially threaded design offers flexibility in precision machinery, allowing the unthreaded portion to act as a dowel for accurate alignment. With a 1/2" hex drive, it ensures maximum torque transfer without stripping, supporting maintenance efficiency in tight spaces.

Specification Summary & Compliance
