Nord-Lock Group

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.

Nord-Lock wedge-locking washers utilise tension instead of friction in order to secure bolted joints exposed to severe vibration and dynamic loads.

Over the operational life cycle, Nord-Lock washers offer increased operational reliability and lower maintenance costs, while significantly reducing the risks of production stops, accidents and warranty claims.

The Expander System is perfect for repairs even if the lugs are badly worn. The expansion sleeves expand to conform to the wear patterns and lock the system into place. There is no need for time-consuming and expensive welding practices. Expander is a long term solution and most repairs are done in the field to minimize your downtime.

Each Expander System comes with a full Lifetime Warranty. We guarantee that your solution will perform as expected from the moment it is installed until the end of its intended lifecycle.

Boltight’s standard range of hydraulic bolt tensioners are designed for general use on top side applications. Each tool comprises of a hydraulic cylinder, bridge, puller and socket.

Interchangeable adaptor kits fit common hydraulic cylinders to enable the tightening of multiple bolt sizes.
