  • The serrated flange design ensures consistent locking force by biting into the mating surface, preventing loosening due to vibration.
  • Zinc plating adds a layer of corrosion resistance, making the nut suitable for a wide range of environments, including outdoor applications.

Applications & Advantages

  • These nuts are particularly useful in applications where high vibration is a concern, such as automotive assemblies, construction equipment, and industrial machinery.
  • The integrated flange distributes pressure over a larger area, reducing the risk of damage to the mating surface and eliminating the need for a separate washer.
  • The serrations provide a self-locking feature, reducing the need for additional locking mechanisms and simplifying installation and maintenance.

Material & Specifications

  • Constructed from high-strength carbon steel, ensuring durability and resistance to shear forces.
  • The zinc coating not only protects against corrosion but also provides a clean, professional finish to the assembled parts.
  • The standard hex shape is compatible with a wide range of tools, allowing for easy installation and removal.

Hardness & Durability

  • Engineered for optimal hardness to resist deformation under load while maintaining enough ductility to avoid brittleness.
  • The combination of the serrated flange and robust material selection contributes to the nut’s overall durability, ensuring long service life even in harsh conditions.

Proof Load & Finish

  • These nuts are designed to meet specific proof load requirements, ensuring reliability in critical applications.
  • The zinc finish provides an additional layer of protection against environmental factors, extending the nut’s lifespan and maintaining its functional integrity.
  • The aesthetic appeal of the shiny zinc finish also enhances the appearance of the final product, contributing to a clean and professional look.
