HV Washers

Hex Nuts

HV washers are high-strength washers designed to distribute loads and protect surfaces in bolted connections. They are specifically engineered for use in high-tension applications, often paired with HV bolts and nuts to ensure secure and reliable joints.

  • High-strength design suitable for structural applications
  • Used to distribute load and protect the surfaces of bolted joints
  • Commonly used in construction, bridges, and steel structures
  • Manufactured according to standards such as EN 14399-6
  • Available in various materials like steel and stainless steel
  • Provides a robust and reliable connection for high-load applications

Spring Washer Applications:

Spring washers are essential in many mechanical and fastening applications. They are designed to provide a constant spring force that helps maintain the tension in the fastener assembly, preventing loosening and compensating for vibrations or thermal expansions. Their unique shape and properties make them valuable in applications where secure and reliable fastening is crucial.

  • Maintaining tension and preventing loosening of fasteners
  • Compensating for vibrations and dynamic loads
  • Absorbing thermal expansion and contraction
  • Providing a reliable connection in high-stress environments
  • Enhancing the longevity and stability of assemblies
  • Commonly used in automotive, aerospace, and machinery applications
