High load capacity due to the externally located teeth on the fixing sleeve.
Direct hammering without pre-drilling into aerated concrete.
Safe screw guidance due to ribbed internal geometry.
High flexibility due to using wood and chipboard screws.
Productomschrijving
The metal anchor for wood and chipboard screws.
Advantages
The metal expansion anchor FMD is especially suited to applications in installation technology.
The external teeth expand in the building material, thus ensuring a high load-bearing capacity.
The ribbed internal geometry of the FMD is suitable for wood and chipboard screws, and makes it possible to guide the screw securely. This offers increased installation safety, and enables a broad range of applications.
The fischer metal expansion fixing FMD is set in the pre-positioned installation. Inserting the screw causes the fixing to expand, and the metal teeth fix the fixing securely in the building material. The fischer metal expansion fixing FMD is particularly suitable for safely fixing gas and water pipes, as well as cable and pipe clamps to solid and hollow building materials as well as in solid gypsum panels.

Montage instructies
Functionality
The FMD is suitable for pre-positioned installation.
Inserting the screw causes the FMD to expand, and the metal teeth fix the anchor securely in the building material.
The required (stud) screw length is given by: Anchor length + plaster and/or insulation layer thickness + fixture thickness or installation spacing + 1 x screw diameter.
Suitable for wood and chipboard screws.
The drill diameter is relative to the compressive strength of the building material. The higher the compressive strength, the greater the drill diameter. The FMD can be hammered directly into low-strength aerated concrete without the need for pre-drilling.
