Product Overview
Metric flange nuts are fastening components designed by adding a flange structure to traditional hex nuts. The bottom flange increases the contact area with connected parts, helping distribute force more evenly and improving connection stability.
Manufactured from stainless steel and carbon steel, these nuts are suitable for applications requiring enhanced support performance or reduced stress concentration on connection surfaces. Compared with standard hex nuts, the flange design provides improved installation adaptability.
Product Features
- Enlarged contact area helps improve load distribution at the connection point.
- Enhances installation stability and reduces the risk of loosening.
- Can reduce the need for additional washers in certain applications.
- Suitable for efficient installation in batch production environments.
- Supports different materials, specifications, and surface treatments.
Applications
Metric flange nuts are mainly used in new energy vehicles, battery systems, energy storage equipment, mechanical equipment, electrical control cabinets, automation equipment, and industrial structural assemblies.
