S-92562A428 10-32 x 3/4" MS16998-29, NAS1351-3-12P 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 in demanding applications.
• Superior corrosion resistance from cadmium plating protects against rust and degradation, extending service life in harsh industrial environments.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies, minimizing loosening in critical machinery.
• Fine UNRF thread spacing offers improved load distribution and better sealing capabilities compared to coarse threads.
• High hardness rating (Rockwell C39) maintains thread integrity and drive socket shape through repeated installation cycles.
• Fully threaded design allows for maximum grip length adjustment and consistent clamping force across the entire fastener length.
• Standard hex socket drive enables high-torque installation with common tools while maintaining a low-profile head for space-constrained applications.
