Product Description

The Fischer universal fixing UX is a plastic fixing made of high-quality nylon. The Fischer universal fixing expands in solid building materials and knots in hollow building materials for maximum hold. For this reason the fischer UX is always the correct choice - even with unknown building materials. The edge prevents slippage during assembly.

Top Features

  • Plug holds in all building materials.
  • Maximum hold in solid and hollow building materials due to knotting.
  • Knots in perforated brick and behind gypsum plasterboard.
  • Optimum screw guidance due to slanting connection bridges.
  • Installation safety due to anti-rotation lock.


  • The universal operating principle (knotting or expanding) allows for use in all solid, hollow and board building materials. Thus the UX is the correct choice for unknown base materials.
  • The UX's angled connection ridges allow for optimum screw guidance. Serrated anti-rotation locks prevent rotation in the drill hole. This guarantees the greatest possible installation safety.

  • The UX with rim is suitable for pre-positioned installation.
  • Turning in the screw causes the UX to expand in the solid building material and to knot within the cavity.
  • The required screw length is given by the plug length + fixture thickness + 1 x screw diameter.
  • Suitable for wood and chipboard screws, as well as stud screws.
  • In the case of board building materials, the threadless part of the screw must not be longer than the fixture, and the UX with rim is to be used.
  • The edge distance must be at least one plug length.
