Nord-Loc Group


In an industrialised world where machinery, vehicles and equipment make up our civilisation, details matter.

Loosening bolts can lead to fatigue failures, unplanned downtime, lost production, excessive maintenance costs and even injury.

From petrochemical and rail industries to power regeneration plants, they require a bolting solution that not only ensures the safety of their employees, projects and investments, but also enables their equipment to push the limits of daily operations.

The Expander system makes repair easy; even if the wear on the lugs is complex, it allows for in-situ repair with minimal downtime. If the bolt shows some wear, the sleeves simply expand according to the wear pattern and fix the system without incurring downtime or costly in-line welding and drilling; simply retighten.

Each Expander system comes with a full Lifetime Warranty. We guarantee that your solution will deliver the expected performance from the time of installation until the end of its life.
