S-90045A461 3/8"-24 Locknuts

Key Features & Benefits at a Glance

• Superior vibration resistance through top lock distorted thread design that maintains secure fastening under dynamic loads
• Excellent corrosion resistance with 18-8 stainless steel construction for extended service life in harsh environments
• Optimal torque transmission via external hex drive design that prevents tool slippage during installation
• Precise thread engagement with Class 2B thread fit ensuring reliable performance in critical applications
• Enhanced holding power from fine thread spacing (24 TPI) that provides superior clamping force distribution
• Industry compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications
• Standard hex profile allowing compatibility with common wrench sizes and tooling systems

Professional Applications & Engineering Value

This 3/8"-24 UNF top lock distorted thread locknut delivers exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The 18-8 stainless steel construction provides inherent corrosion resistance, making it ideal for chemical processing, marine environments, and outdoor equipment where moisture exposure is common. The distorted thread locking mechanism at the top section creates controlled interference that maintains clamp load without requiring additional locking elements, simplifying assembly while reducing component count. The external hex drive configuration ensures maximum torque application capability, particularly valuable in high-stress industrial fastening scenarios. With fine thread spacing and Class 2B thread fit, this locknut offers precise installation characteristics for machinery, automotive subsystems, and precision equipment where dimensional stability under thermal cycling is critical.

Specification Summary & Compliance

This locknut features 3/8"-24 UNF right-hand threads with Class 2B thread fit tolerance for consistent engagement. The top lock distorted thread design conforms to industrial locking fastener principles while the standard hex profile (9/16" width) ensures tool compatibility. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental compliance for global supply chain integration. The 21/64" height provides optimal thread engagement while maintaining compact dimensions for space-constrained applications.
