S-94920A500 M8 Flange Nuts

Key Features & Benefits at a Glance

• Exceptional vibration resistance through precision serrations that bite into surfaces, preventing loosening under dynamic loads
• Enhanced load distribution with 18.25mm flange diameter, reducing surface pressure and material damage
• Heavy-duty performance guaranteed by Class 8 steel construction, suitable for high-stress industrial applications
• Reliable coarse thread engagement with M8x1.25mm metric threading for quick assembly and superior holding power
• Secure Class 6H thread fit ensuring precise mating with bolts and consistent clamping force
• Easy installation and removal using standard 13mm external hex drive tools
• Environmental compliance with RoHS 3 standards, making it suitable for regulated industries

Professional Applications & Engineering Value

This Class 8 steel flange lock nut delivers critical vibration resistance where conventional fasteners fail. The serrated locking mechanism creates permanent bite into mating surfaces, eliminating the need for additional locking components in automotive assemblies, heavy machinery, and industrial equipment. The integrated 18.25mm flange acts as a built-in washer, distributing clamp load over wider areas to prevent surface damage to softer materials. Manufactured from high-grade steel with metric coarse threading (M8x1.25mm), this nut maintains integrity under extreme vibration and thermal cycling, making it ideal for engine components, conveyor systems, and structural frameworks where reliability is non-negotiable.

Specification Summary & Compliance

This M8 flange lock nut features Class 6H thread fit per metric standards with 1.25mm coarse pitch right-hand threading. Dimensions include 13mm width across flats, 7mm height, and 2.6mm flange thickness. Manufactured to Class 8 strength rating and fully compliant with RoHS 3 (2015/863/EU) environmental regulations, ensuring reliability and safety in professional applications.
