The Nord-Lock Group manufactures patented Superbolt multi-jackbolt tensioners designed to eliminate unsafe and time consuming bolting methods. MJTs replace or retrofit existing nuts and bolts, and only require hand/air tools for installation and removal of any size tensioner.

Thousands of companies have enjoyed the benefits of using our bolting products. Switching from other bolting methods (such as hydraulic torque wrenches and stud heaters) can save you money and increase worker safety. Also, MJT\'s offer a better bolted connection than conventional hex nuts. Discover all the benefits below!
