S-92423A131 10-32 x 2 3/4" ASME B18.3, NAS1351N3-44, SAE AMS5731, SAE AMS5737 High-Strength A286 Stainless Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional Strength & Reliability: With a tensile strength of 160,000 psi and yield strength of 120,000 psi, this screw provides superior load-bearing capacity and resistance to deformation in high-stress applications.
• Superior Corrosion Resistance: The passivated finish on A286 stainless steel significantly enhances durability, protecting against rust and degradation in harsh industrial environments.
• Precision Fit for Secure Fastening: The Class 3A thread fit ensures tight, reliable engagement with mating parts, minimizing the risk of loosening under vibration or dynamic loads.
• High-Temperature & High-Strength Material: A286 stainless steel, hardened to Rockwell C33, maintains its mechanical properties and resists creep at elevated temperatures.
• Optimized for Efficient Installation: The internal hex drive (5/32") and standard socket head profile allow for high torque application and easy installation in confined spaces.
• Fine Thread for Enhanced Clamping: The UNRF fine thread provides a higher number of threads per inch, offering improved adjustment and better retention in materials prone to stripping.
• Regulatory Compliance & Quality Assurance: Manufactured to meet ASME B18.3, NAS1351N3-44, and SAE AMS5731/5737 standards, ensuring consistent quality and performance for critical applications.

Professional Applications & Engineering Value

This 10-32 Socket Head Cap Screw is engineered to solve critical fastening challenges in demanding sectors like aerospace, automotive, and heavy machinery. The core value lies in its A286 stainless steel composition and passivated finish, which work in tandem to combat corrosion and maintain integrity under extreme thermal and mechanical stress. The UNRF fine thread and Class 3A fit deliver a precise, vibration-resistant connection, crucial for assemblies where safety and reliability are paramount. Its partially threaded design allows the unthreaded shank to act as a precise dowel, providing superior alignment and shear strength. This combination of material excellence and dimensional precision makes it an ideal choice for high-performance engines, structural frames, and precision instrumentation, directly addressing the need for durable, long-lasting fasteners that reduce maintenance cycles and prevent costly failures.
