S-92196A376 3/8"-24 x 5" 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
• High tensile strength of 70,000 PSI ensures reliable performance under heavy loads and vibration
• Precision Class 3A thread fit provides superior engagement and reduces the risk of cross-threading in critical assemblies
• Fine UNF threading offers improved adjustment control and better load distribution compared to coarse threads
• Partially threaded design allows for secure clamping without unnecessary thread engagement in non-critical sections
• 5/16" hex drive socket enables high-torque installation with standard tools, minimizing stripping risks
• Rockwell B70 hardness enhances wear resistance and maintains thread integrity through repeated use

Professional Applications & Engineering Value

This 3/8"-24 UNF socket head cap screw delivers critical performance in precision machinery, automotive systems, and heavy equipment where vibration resistance and corrosion protection are paramount. The 18-8 stainless steel material combats oxidation in humid or chemical-exposed environments, while the fine thread spacing and Class 3A fit ensure zero-backlash fastening in high-tolerance applications. Engineers specify this partially threaded fastener for fixtures, jigs, and structural frames requiring exact clamp force without thread interference. Its 5-inch length and standard socket head profile make it suitable for deep recess installations where wrenches cannot reach, maintaining assembly integrity under dynamic stresses.

Specification Summary & Compliance
