Superbolt was the world's first to revolutionize nuts and bolts with the multi-jackbolt tensioner (MJT) in 1984. Since then, Superbolt has proven its technology in tens of thousands of successful installations. Superbolt tensioners are easy to work with and provide an overwhelming mechanical advantage with their unique design, which divides the load among multiple small jackbolts. Once installed properly, MJT connections are reliable, and can stay tight indefinitely. Even MJTs of enormous sizes are safe and can be installed or removed by a single worker with ordinary hand tools.
But the revolution hasn't stopped here. Superbolt continues to develop a multitude of solutions to solve the next generation of bolting challenges. With the widest range of tensioners on the market and constant growing portfolio, Superbolt has got you covered.
