Product Description
Our Flange Nut, manufactured to the precise DIN 6923 standard, is a high-performance fastening solution that combines a hex nut with an integrated, non-rotating flange. This design eliminates the need for a separate washer, reducing assembly time and inventory costs. The flange features concentric serrations (zig-zag teeth) on its bearing surface that bite into the contact material, providing exceptional resistance to loosening under severe vibration and dynamic loads. Heat-treated to Grade 8 mechanical properties, this nut ensures a reliable, high-strength connection. The clear zinc plating offers effective corrosion protection and a clean, industrial finish, making it a versatile and robust choice for demanding applications in automotive, machinery, and structural assembly.

Application Scenarios
This serrated flange nut is engineered for high-vibration environments where safety is critical:
- Automotive Chassis and Engine Mounting: Widely used in suspension system assembly, engine mounting brackets, and exhaust system fastening to prevent loosening from constant vibration.
- Heavy Machinery and Equipment Assembly: Ideal for securing hydraulic components, vibrating conveyor frames, agricultural equipment, and construction machinery.
- Electrical Panel and Control Cabinet Manufacturing: Used to secure heavy electrical components and busbars within panels, where the serrations ensure electrical continuity and a solid ground.
- Transportation and Trailer Manufacturing: Essential for wheel hub assembly, trailer hitch connections, and body panel attachment in trucks and trailers.
- Industrial Robotics and Automation: Provides reliable fastening for robotic arm joints, linear guide mounts, and other precision equipment susceptible to micro-vibrations.
- General Maintenance, Repair, and Operations (MRO): A versatile upgrade for factory maintenance kits, replacing standard nut/washer combinations for improved reliability.
