Brass fixing MS

The brass expansion fixing with metric thread

The fischer anchor MS is an expansion plug made from a brass sleeve with a brass cone for holding a metric thread. The expansion plug is suitable above all for fixing aggregates, control boxes and shelves in concrete and masonry made from solid building materials. The fischer MS is set in a pre-positioned installation. As the screw or threaded rod is rotated, the internal brass cone expands and the plug anchors itself against the wall of the drill hole. The compact design of the brass fixing saves time and costs when drilling and installing.

Product Description


  • The compact design of the brass fixing reduces the amount of drilling required, helping to ensure a fast installation.

  • The special surface structure of the MS prevents the fixing from rotating in the drill hole. This provides increased installation safety.

  • The internal thread allows for the use of standard metric screws or threaded rods, and for surface flush removal and reuse of the fixing point. This provides great flexibility.

Assembly Instruction


  • The MS brass fixing is suitable for pre-positioned and push-through installation.

  • Turning in the metric screw causes the front part of the brass fixing to expand, thus securely anchoring it in the substrate.

  • Calculating screw length for flush fixing installation: Fixing length + fixture thickness = min. screw length.

  • Suitable for metric screws and threaded bolts.

  • The brass fixing may have to be expanded slightly before installation by turning in the threaded screw.
