A HYTORC NUT tensioning nut is a mechanical tensioner which allows to tighten a bolt in pure tension with a torque tool. This nut is made in 3 pieces to protect the bolted assembly from friction and wear.
A ring at the base ensures contact without movement on the bearing surface, a threaded insert accompanies the longitudinal stroke of the threaded rod without rotation and the force is transmitted by an external sleeve which only rubs on the other 2 parts.
There are 3 types ofHYTORC NUT tensioning nuts according to the needs: type TN when the threaded rod does not protrude from the nut, type CN when the threaded rod protrudes from the nut or type SN when the nut has to be driven by a hydraulic wrench.
