HYTORC Nut Tensioning Nut

The HYTORC NUT tensioning nut is a 3-piece pre-tensioning system for applications where high demands are placed on the bolted connection. The HYTORC Nut converts a rotating force (torque) into a stretching force (tension). Because the inner and outer nut rest on each other, bending forces do not play a role. The bolt can move with the inner nut and the integrated washer prevents the nut from rotating directly over the flange surface. The bolts are fully mechanically tensioned.

The only system in the world that comes pre-calibrated to bolt load. With the HYTORC NUT, you work hands-free, without a reaction arm and without a counterholding key.

  • Prevents galling and loosening of bolted connections
  • Individually calibrated so extremely accurate and consistent
  • Prevents damage to the flange surface
  • Easy and quick to disassemble joints that have been stuck under high temperatures for a long time.

Very little space required

With an outer diameter of only 1.6 × internal thread diameter, the HYTORC Nut is smaller than a hex nut.

HYTORC Nut

Accuracy of ±5 %

Thanks to the unique design of the HYTORC Nut, the bolt is preloaded torsion-free and up to the yield point

HYTORC Nut

Temperature-resistant and reusable

The HYTORC expansion nut is designed for temperature ranges up to 320° C or 450° C. The system has distinct advantages in terms of re-usability, quick disassembly and assembly.
