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.
Superbolt multi-jackbolt tensioners (MJTs) take the high preload requirements in large diameter bolting and break it down into manageable torques using the jackbolts threaded through the nut body.
Superbolt expansion bolts are truly fitted into the hole due to the radial expansion of the conical bore sleeve.
By design, accurate radial force combined with the known axial clamping load, provides total protection against coupling slippage and thus prevents bolt and hole damage during subsequent removals.
The expansion bolts can be retrofitted to replace traditional interference or force fitted bolts, reliably and cost-effectively.
