Screw-in tool for stud bolts

Product information

  • The screw-in tool limits the scew-in depth of a threaded pin into an undercut anchor.
  • The threaded pin is inserted into the tool and screwed into the undercut anchor up to the stop.
  • The integrated hinge in the screw-in tool ensures that the threaded pin remains in position in the undercut anchor when the tool is unscrewedf from the pin.
  • This ensures that the threaded pin is mounted flush with the tip of the undercut anchor. The correct screw-in depth has to be monitored.
  • The individual protrusion has to be determined for every combination of undercut anchor and threaded pin length.
  • For further information please refer to the assembly instructions.
