CY Style Nut Tensioners

Superbolt cy style mechanical tensioners.  More powerful tha the Superbolt MT standard.
CY series tensioners are used for higher bolt loads on general machinery applications where more clamping force is needed than can be achieved with the MT style tensioner. They fit in the same area as a heavy hex nut.
