The structure and principle of operation are similar to the "normal" step nut, where the inner part is higher and an external thread for inclusion of a "blocking ring” exists.
After the clamping procedure, the blocking ring can be screwed up to the system and pressure can be released. The clamping element now holds the force "mechanically blocked".
Dimensions are produced according to the customer's wishes.
Area of application: enable extremely long clamping cycles
