S-92196A697 9/16"-18 x 1 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 fastening strength and reliability from a high 70,000 psi tensile strength and Rockwell B70 hardness, preventing stripping and failure under heavy loads.
• Precise, secure thread engagement with a Class 3A UNF fine thread fit, ensuring vibration resistance and a tight, reliable seal in critical assemblies.
• High-torque installation capability using the standard 7/16" hex drive, allowing for secure tightening in confined spaces without cam-out.
• Full-length threading (1-1/2") provides maximum adjustability and grip length, offering versatile fastening solutions for various material thicknesses.
• Guaranteed dimensional consistency and interchangeability through compliance with the rigorous ASME B18.3 standard.
• Safe for regulated industries with full compliance to RoHS 3 and REACH environmental regulations, ensuring no hazardous substances are used.

Professional Applications & Engineering Value

This Socket Head Cap Screw is engineered to solve critical challenges in demanding applications. The 18-8 Stainless Steel material provides excellent resistance to rust and corrosion, making it a top choice for machinery, marine equipment, and chemical processing plants where moisture and corrosive agents are present. The 9/16"-18 UNF fine thread and Class 3A fit offer superior resistance to loosening under vibration compared to coarse threads, which is vital for automotive, aerospace, and precision equipment assemblies. The combination of high tensile strength and the reliable hex drive ensures that these fasteners can be installed with high torque to clamp components securely, preventing joint failure and maintaining structural integrity in high-stress environments.
