S-94920A300 M5 Flange Nuts

Key Features & Benefits at a Glance

• Superior vibration resistance through serrated locking design that bites into mating surfaces, preventing loosening under dynamic loads
• Enhanced load distribution with 11.2mm flange diameter that reduces surface pressure and prevents material damage
• High-strength performance with Class 8 steel construction ensuring reliable performance in demanding industrial applications
• Quick installation using standard 8mm external hex drive compatible with common wrench tools
• Precise thread engagement with Class 6H metric coarse thread (M5x0.8) ensuring consistent, reliable fastening
• Environmental compliance meeting RoHS 3 standards for use in regulated industries and international markets
• Space-efficient design combining flange and locking functions in a compact 4.3mm height profile

Professional Applications & Engineering Value

This M5 flange lock nut delivers critical vibration resistance where conventional fasteners fail. The serrated locking mechanism creates permanent friction against mating surfaces, eliminating the need for additional locking components in high-vibration environments like machinery, automotive assemblies, and electrical enclosures. Manufactured from Class 8 steel, this metric hex nut maintains clamping force under extreme conditions while the integrated 11.2mm flange distributes load across wider areas, preventing surface damage to softer materials. The coarse thread pitch (0.8mm) ensures rapid installation and superior resistance to vibration-induced loosening, making it ideal for production lines requiring both speed and reliability.

Specification Summary & Compliance

This flange lock nut features M5x0.8 metric coarse threads with Class 6H thread fit tolerance, ensuring precise engagement with mating components. The external 8mm hex drive provides standard tool compatibility while the 11.2mm flange diameter and 1.75mm thickness deliver optimal load distribution. Manufactured to Class 8 strength rating standards and compliant with RoHS 3 (2015/863/EU) environmental regulations, this nut meets rigorous industrial requirements for performance and safety in global markets.
