• Maintains high clamp load and thereby ensures the function of the joint
• Quick and easy to install and remove with standard tools
• Locking function not affected by lubrication
• Defined and uniform friction conditions which result in a more accurate pre-load
• Same temperature characteristics as standard bolt / nut
• Reusable - do not affect the reusability of fasteners
• The washers are hardened and can support and distribute great loads
• High corrosion resistance
• Can be used with fasteners up to grade 12.9 (ASTM A574)
• Reliable locking, even for joints with short clamp length
• Secures fasteners at both high and low pre-loads
• No retightening needed
• Verifiable locking function
• Minimum 600 hours in salt spray test
