Customized solutions

The Nord-Lock Group is a pioneer in innovative bolting solutions and we’re always looking for new challenges to overcome. If you’re experiencing a bolting issue, you can rely on us find the most efficient and cost-effective solution.

 

One-off design 

If one of our existing tools cannot be modified, we will design and manufacture equipment to suit. This can be supplied to fit any size of bolt and deliver any load requirement. We have produced tensioners for bolts ranging in size from M8 to over M400. Designs are usually completed within a few days with production timescales dependent on the size of the order. Whatever the requirement, Boltight is committed to offering a fast turnaround. 

 

Modifications to standard tools 

For many applications, the best approach is to adapt one of our existing tools to meet a customer's specification. This might involve manufacturing the tensioner with a special threaded section, a different puller bar or a cutout to clear adjoining nuts or weld bead. Modifications like these to stock items can be turned around quickly with minimal or zero cost penalty.
