CY - High strength tensioner

Nut-style multi-jackbolt tensioners (MJTs) are an innovative bolting product that will eliminate expensive and dangerous tooling. Only hand/air tools are required to install or remove any size MJT.


CY series tensioners are used for higher bolt loads on general machinery applications. They fit in the same area as a heavy hex nut.
