S-97400A102 M8 DIN 6923 Flange Nuts

Key Features & Benefits at a Glance

• Vibration-resistant locking with precision serrations that bite into mating surfaces to prevent loosening under dynamic loads
• Enhanced corrosion resistance from 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Integrated flange design distributes clamping pressure over wider surface area, reducing damage to assembled materials
• High-torque capability through external hex drive design that enables secure installation with standard wrenches
• Precision thread engagement with Class 6H thread fit and M8x1.25 coarse pitch for reliable fastening in various materials
• Regulatory compliance assurance meeting DIN 6923 standards plus REACH and RoHS 3 environmental directives
• Reduced assembly complexity by combining flange and locking functions in a single component

Professional Applications & Engineering Value

This M8 flange lock nut delivers critical vibration resistance where traditional fasteners fail. The 18-8 stainless steel construction provides excellent corrosion resistance for demanding applications in automotive, machinery, and structural assemblies exposed to moisture or chemicals. The integrated serrated locking mechanism eliminates the need for separate washers or thread-locking compounds, streamlining assembly while maintaining secure fastening under continuous vibration. The external hex drive allows for high-torque installation with common tools, while the 17.9mm flange diameter creates a stable bearing surface that prevents pull-through in softer materials. Engineered to DIN 6923 standards, this metric flange locknut ensures compatibility with international equipment specifications and replacement part requirements.
