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 is at the core of Superbolt® technologies. With Superbolt NXT, 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 other user-friendly features elevates Superbolt NXT.
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.
Superbolt NXT also features a black oxidised coating for corrosion protection, laser-markings to guide installation and an anti-slip knurling grip layer.
Superbolt NXT is available from September 2022.
