Product features

• Specifically developed for the requirements of electrical current-carrying bolted contacts
• Arc-shaped spring geometry compensates for settlement and thermal expansion effects while maintaining preload
• Protects the bearing surface through the specially embossed runner shape and prevents relative rotation of the washer on soft bearing surfaces
• Reliable resistance to self-loosening under vibration through the locking effect beneath the bolt head or nut provided by the advanced serration
• Increased outer diameter for elongated and special hole geometries
