The distinguishing feature of the Bolt Tensioners of product group 2 is that the cylinder-piston-set is placed over a continuous bolt thread and that, then, the tension nut is screwed down to the stop face of the piston.

Main Features


  • single-stage
  • tension nut
  • for continuous bolt threads

Advantages of PG
  • SSV simple to place, thus short set-up times
  • cost-efficient continuous bolt thread
  • easy handling because of low weight of tension nut
    when screwing on and off

Examples of Applications
  • where bolts are tensioned to yield stress limit or for
    economic reasons where continuous thread is chosen
  • machine building
  • · anchoring

More SSV

We distinguish our Bolt Tensioners into 8 different product groups (designs)
which, in principle, have all the same function.
