Horizon Inc.

Our products are based on leading wedge locking technology and are recognized for their ability to safely secure bolted joints exposed to severe vibration and dynamic loads. 

Nord Lock Wedge-Locking Technology:

Nord-Lock washers secure bolted joints with tension instead of friction. The system is comprised of a pair of washers with cams on one side and radial teeth on the opposite side. Since the cam angle 'a' is greater than the thread pitch 13' a wedge effect is created by the cams, preventing the bolt from rotating loose. 

• 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 bads 
• Washers with enlarged outer diameter available for flanged bolts/nuts 
• High corrosion resistance 
• Can be used with fasteners up to grade 129 (ASTM A574) 
• Reliable locking. even for joints with short clamp length 
• Secures fasteners at both high and low preloads 
• No re tightening needed 
• Verifiable locking function 
• Elegant Solution and problem solving-modern engineering
