Superbolt Load-Sensing Tensioner - Nord-Lock Group

Nord-Lock Group About Superbolt Products Load-Sensing Tensioner

Superbolt was the world’s first to revolutionize nuts and bolts with multi-jackbolt tensioning (MJT) technology. 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.

Easy preload measurement

A true innovation in the field of preload monitoring, the Superbolt Load-Sensing Tensioner (LST) is among the first of Nord-Lock Group’s Industry 4.0 products.

Equipped with a strain-measuring device, the patented LST analyzes the variation of the tensioner’s circumference in proportion to the variation in bolt preload. Additionally, the LST offers remote monitoring and a live reading of data – all with an accuracy that is better than +/-5%!
