The expansion plug for metric screws and threaded bolts
Expansion plug M-S
The fischer anchor M-S is an expansion plug made from high-quality nylon for screws and threaded rods with a metric thread. The fischer anchor M-S is ideal for fixing handless, folding shutters or downpipes in concrete, aerated concrete, solid gypsum panels and other solid and hollow building materials. The special anchor can be used in pre-installation and the time-saving push-through installation. When screwing in the screw, the M-S expands and anchors itself in the drill hole. The slimline plug geometry makes it easy to push the plug into the drill hole, for a fast and simple installation.
The internal geometry of the M-S allows for the use of standard metric screws or threaded rods for the ideal adaptation to suit the intended use.
The rimless plug sleeve allows for the plug to be set as deep as required below the plaster to the bearing substrate to achieve the maximum load-bearing capacity.
As the plug only expands in two directions, it is possible to direct the expansion forces so that they run parallel to the edge of the building material by turning the plug. This allows for smaller edge distances.
The slimline plug geometry makes it easy to push the plug into the drill hole, for a fast and simple installation.

Perforated sand-lime brick
Solid sand-lime brick
Natural stone with dense structure
Solid brick made from lightweight concrete
Solid panel made from gypsum
Vertically perforated brick
You can find detailed information on building materials in the approval document.
The M-S is suitable for pre-positioned and push-through installation.
When turning in the screw, the M-S expands in two directions, thus providing a secure anchoring in the building material.
The required screw length is given by: Plug length + plaster and/or insulation layer thickness + fixture thickness + 1 x screw diameter.
Suitable for metric screws and threaded bolts.
Chamfer the thread to make it easier to screw in screws and threaded rods.
