Description
Grade 5 serrated flange nuts are commonly used in applications where vibration resistance and a secure grip are essential. The serrations on the flange create a locking effect by biting into the surface, preventing loosening. Some common applications include:
  1. Automotive Industry – Used in engine mounts, suspension systems, exhaust assemblies, and chassis components to prevent loosening due to vibrations.
  2. Heavy Machinery and Equipment – Securing bolts in construction, agricultural, and industrial machinery that experience continuous movement and load shifts.
  3. Manufacturing and Assembly – Fastening components in conveyor systems, automated machines, and robotics where vibration and motion are present.
  4. Electrical and Power Generation – Used in generators, turbines, and switchgear to ensure a firm and secure connection.
  5. Piping and Plumbing – Helps secure flanges and other pipe connections without the need for additional lock washers.
  6. Structural Applications – Common in metal buildings, steel frameworks, and heavy-duty construction projects where a strong and vibration-resistant hold is required.
Serrated flange nuts are especially useful in applications where traditional lock washers or separate washers would be inconvenient or unnecessary. Coated in zinc with a clear trivalent finish to withstand 72 hours until the appearance of red rust.
