Nord-Lock
Nord-Lock Washers - Wedge Lock Solution:
Nord-Lock washers provide more than just a safe locking function, using our washers also improves the general performance of a bolted joint.
Product Benefits
• 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 preload
• Same temperature characteristics as standard bolt / nut
• Reusable – in addition, Nord-Lock washers do not
affect the reusability of fasteners
• The washers are hardened and can support and
distribute great loads
• Washers with enlarged outer diameter available
for flanged bolts / nuts
• 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 preloads
• No retightening needed
• Verifiable locking function
• Elegant solution and problem solving – modern
Engineering
Proven in Junker Vibration Test
The Junker test, according to DIN 65151, is considered the most severe vibration test for bolted connections. During the test, the joint is exposed to transverse movements underneath the bolt head / nut, while the clamping force is continuously measured.
