Using the zWasher Smart Disk, a screw connection can be assembled and disassembled axially with no bending torque and without a support arm. This procedure allows the required pre-tensioning force to be achieved with much higher precision and prevents damage to the components.



When connecting the screw and the nut, the appropriate zWasher counter-washer must also be placed beneath the nut.



Overview of advantages:



  • No need for a support arm

  • Screw connection with no lateral load

  • Less equipment required for assembly

  • High pre-tensioning accuracy

  • Low tool weight

  • Transmission of precise, high torques

  • Easy to use

  • Greatly reduced risk of accidents

  • Increases reusability of the connecting elements

  • Protects the machine contact surfaces

  • Reduced load on the tool


Burnished in line with DIN 50938
