S-92562A367 3/8"-16 x 2 3/4" MS16997-106, NAS1352-6-44P Mil. Spec. Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 160,000 PSI ensures reliable performance under high-stress conditions, reducing the risk of fastener failure.
• Superior corrosion resistance provided by the cadmium plating on alloy steel, extending service life in harsh industrial environments.
• Precise Class 3A thread fit guarantees secure, vibration-resistant connections, minimizing loosening in critical assemblies.
• High hardness rating (Rockwell C39) enhances wear resistance, maintaining thread integrity through repeated use.
• Coarse UNRC threads enable quick and easy installation, saving time in high-volume production settings.
• Partially threaded design offers optimal grip and clamping force where full threading isn't required, improving assembly versatility.
• Compliance with MS16997-106 (NAS1352-6-44P) ensures adherence to stringent aerospace and industrial standards, providing quality assurance for regulated applications.

Professional Applications & Engineering Value

This cadmium-plated alloy steel socket head cap screw is engineered to address common industrial challenges such as vibration-induced loosening and environmental degradation. The coarse UNRC thread with Class 3A fit provides superior holding power in high-vibration machinery, automotive assemblies, and heavy equipment. The 160,000 PSI tensile strength and Rockwell C39 hardness make it ideal for applications demanding high clamp load and durability, such as in aerospace frameworks, construction machinery, and precision manufacturing jigs. The cadmium plating offers an added layer of corrosion resistance, ensuring long-term reliability in exposed or chemically aggressive environments, while the hex drive socket head allows for high-torque installation in confined spaces.
