Description
Grade 5 serrated flange bolts are commonly used in applications requiring high resistance to loosening due to vibration. The serrations under the flange grip the material surface, preventing back-off. Some common applications include:
  1. Automotive Industry – Used in engines, chassis, suspension, and exhaust systems where vibration resistance is critical.
  2. Heavy Machinery and Equipment – Common in construction, agricultural, and industrial machinery to secure components subjected to constant movement.
  3. Manufacturing and Assembly Lines – Used in conveyor systems, robotics, and automated equipment to maintain secure fastenings under dynamic conditions.
  4. Electrical and Power Generation – Securing components in turbines, generators, and electrical enclosures, where reliability is essential.
  5. Piping and Plumbing – Used in flanged pipe connections to ensure a tight seal without the need for lock washers.
  6. Structural Applications – Fastening steel frameworks, metal buildings, and heavy-duty equipment where a secure hold is needed.
Serrated flange bolts eliminate the need for separate washers and provide better grip, making them ideal for high-vibration environments. Coated in zinc with a clear trivalent finish to withstand 72 hours until the appearance of red rust.
