Nord-Lock Group is a world-leading manufacturer of bolting technologies, with over 35 years of experience solving the toughest bolting challenges.
Our product lines include:
Nord-Lock Wedge Locking Washers, which are recognized around the world for their unique ability to keep bolted joints secure, under any amount of vibration. Joints secured with Nord-Lock washers will not loosen unintentionally, as it creates a wedge-locking effect under the bolt head or nut.
Superbolt Multi-Jackbolt Tensioners (MJTs) eliminate unsafe and time consuming tightening methods for larger diameter bolts. MJTs replace or retrofit existing nuts and bolts, only requiring hand/air tools for installation and removal of the tensioner and achieving an accurate preload. These tensioners can be safely used in fuse bolt applications to ensure precise preload.
Expander System is a permanent solution for pivot pin wear, eliminating the need for welding and line boring while allowing broader tolerances.
Boltight hydraulic tensioning solutions offer advanced technology in critical applications.
