The Easiest-To-Use Bolt Tensioner in The World

Superbolt®, the original inventor and standard-bearer for multi-jackbolt tensioning, introduces Superbolt NXT – a revolutionary bolt tensioner that is up to 30% faster to install than existing solutions. 

Safely reducing the installation and maintenance time of tightening large bolts has long been at the core of Superbolt technologies. With Superbolt NXT, a brand new multi-jackbolt tensioner, Nord-Lock Group is taking those capabilities to the next level. 

Everything has been designed with user simplicity, safety and speed at the forefront. A typical M76 multi-jackbolt tensioner can have up to twelve individual jackbolts, whereas the M76 Superbolt NXT achieves the same secure preload with just eight. 

This, plus a new knurling grip layer to support with handling during installation and removal, and a host of other user-friendly features elevates Superbolt NXT to the easiest-to-use bolt tensioner in the world. 

“It started with a strategic initiative to improve the customer experience when using a Superbolt multi-jackbolt tensioner,” says Sébastien Bruyas, Strategic Sales Manager for Nord-Lock Group. 

The key improvement has been reducing the number of jackbolts required to tighten the bolt, as a small decrease in jackbolts can deliver a large decrease in the tightening time. To achieve this, design engineers had to rethink this critical component. 

We worked with some of the best steel mills and heat treatment partners in the world to get the right materials and processes to increase the strength of our jackbolts. Now, we can offer the customer an equivalent preload with less jackbolts, so it’s faster and easier to install with less torque” says Max Bastiaansen, R&D Project Manager for Nord-Lock Group. 

“Take two products side-by-side, and you will see a visible difference between Superbolt NXT and a competitive multi-jackbolt tensioner – it might have two, four or six fewer jackbolts” adds Bruyas. 

Superbolt NXT also features a black oxidised coating for corrosion protection, laser-markings to guide installation and an anti-slip knurling grip layer. It is instantly recognizable in comparison to the grey tensioners available on the market until today. 

“To design something that just looks good, it’s a bit limited, but we’ve added features that bring a great benefit to the user. Superbolt NXT is easy to recognise, but it’s even easier to use,” says Bruyas. 

Superbolt NXT is available from September 2022. To find out more visit www.nord-lock.com/nxt

About Superbolt 

Superbolt was the world’s first to revolutionize nuts and bolts with multi-jackbolt tensioning (MJT) technology. As the original inventor (Link to You Tube video), Superbolt has been eliminating common bolting problems caused by the loosening of large conventional nuts and bolts since 1974. Our technology has been proven in tens of thousands of successful installations and we continue to develop a multitude of solutions to solve the next generation of bolting challenges. 

High-tech production facilities in Pittsburgh, US and St. Gallenkappel in Switzerland maintain worldwide availability, supported by sales engineers in more than thirty-five international offices and seven technical support centres. Nord-Lock Group works in close partnership with customers to solve complex bolting challenges.
