S-92423A160 3/8"-16 x 4" ASME B18.3, NAS1352N6-64, SAE AMS5731, SAE AMS5737 High-Strength A286 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 160,000 psi ensures reliable performance under extreme loads, minimizing the risk of fastener failure in critical assemblies.
• Superior corrosion resistance from A286 stainless steel and passivated finish provides long-term durability in harsh environments, reducing maintenance and replacement costs.
• Precision Class 3A thread fit guarantees tight, secure connections with minimal backlash, enhancing assembly accuracy and vibration resistance.
• High-temperature stability inherent in A286 material maintains mechanical properties in elevated temperature applications common in aerospace and industrial settings.
• Hex socket drive design allows for high torque application and easy installation in confined spaces, improving assembly efficiency.
• Compliance with multiple industry standards including ASME B18.3 and NAS1352N6-64 ensures consistent quality and interchangeability in regulated applications.
• Partially threaded shank provides optimal grip length where needed while allowing for clearance in non-threaded sections, improving joint integrity.

Professional Applications & Engineering Value

This A286 stainless steel socket head cap screw delivers critical performance advantages in demanding engineering applications where failure is not an option. The combination of 160,000 psi tensile strength and 120,000 psi yield strength provides a significant safety margin for high-stress applications in aerospace frameworks, heavy machinery, and precision equipment. The passivated finish enhances the natural corrosion resistance of A286 stainless steel, making these fasteners ideal for environments exposed to chemicals, moisture, and temperature extremes. The Class 3A thread fit with UNRC coarse threads ensures rapid assembly while maintaining vibration resistance, reducing installation time without compromising joint security. These characteristics make this socket head cap screw particularly valuable in applications requiring both high strength-to-weight ratios and long-term reliability under cyclic loading conditions.
