S-92196A816 5/8"-11 x 5 1/2" ASME B18.3 18-8 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments and extended service life.
• Superior load-bearing capability from a high 70,000 psi tensile strength, ensuring reliable performance under significant stress.
• Precise and secure fastening with a Class 3A thread fit, minimizing the risk of loosening in high-vibration applications.
• Optimized for high-torque installation using a standard 1/2" hex drive, providing a secure grip and reducing tool slippage.
• Enhanced durability and wear resistance due to a Rockwell B70 hardness, maintaining thread integrity through repeated use.
• Versatile partial threading allows for a non-threaded shank section, providing precise clamping control in assembled components.
• Broad industry compliance with ASME B18.3, RoHS 3, and REACH, ensuring material safety and meeting global regulatory standards.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, this 5/8"-11 UNC Socket Head Cap Screw provides a robust fastening solution where reliability is critical. The 18-8 Stainless Steel material offers excellent resistance to corrosion and oxidation, making it suitable for outdoor, marine, or chemical processing equipment. Its coarse thread spacing (UNC) and Class 3A thread fit ensure quick assembly and a tight, secure connection, reducing the risk of vibrational loosening in machinery and heavy-duty assemblies. The partially threaded design allows the unthreaded shank to bear shear loads effectively, while the socket head with a 1/2" hex drive facilitates installation in confined spaces with standard tools. This combination of high tensile strength and precision engineering delivers long-term performance in construction, automotive, and manufacturing sectors.
