Nord-Lock Inc.  

  • Booth: 1613

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.

  • Nord-Lock Washers
    Nord-Lock's original wedge-locking technology that secures bolted joints, even when exposed to severe vibration and dynamic loads. It is impossible for our products to loosen unintentionally due to the wedge created underneath the bolt head and nut....

  • Nord-Lock wedge-locking technology secures bolted joints with tension instead of friction. The system is composed of a pair of lock washers with cams on one side and radial teeth on the other.

    Nord-Lock wedge-locking products secure the fastener in a joint which cannot be loosened even when subjected to extreme vibration or dynamic loads. The Nord-Lock range includes washers made from a variety of materials and using a variety of coatings, to ensure performance in whatever conditions your applications require.

    Bolted joints fail for two reasons - spontaneous bolt loosening and slackening. Nord-Lock multifunctional wedge-locking technology tackles both.

    The wedge-effect prevents spontaneous bolt loosening, whilst the spring effect compensates for loss of preload due to slackening – offering you total security for those situations when there can be no compromise.

  • Superbolt tensioners offer you simple and cost-effective tightening of large size bolts. Your joints can be tightened with high accuracy without requiring specialized skills or heavy tooling.

    A wide range of tensioners is available in the standard series, as well as an unlimited capacity to create special designs to meet your unique needs.

    Superbolt multi-jackbolt tensioners take high preload requirements and break them down into manageable torques using the jackbolts threaded through the nut body. They remain easy to install, even on larger sizes, compared to standard hex bolts.
