The fischer metal expansion anchor FMD is particularly suitable for securely fixing gas and water pipes, cable and pipe brackets in concrete, aerated concrete and solid and hollow building materials, as well as in solid gypsum panels. The special anchor is used in the pre-positioned installation, hammered directly into aerated concrete without pre-drilling. Inserting the screw causes the plug to expand, and the metal teeth fix the anchor securely in the building material. The ribbed internal geometry of the FMD makes it possible to guide the screw securely. The use of wood and chipboard screws increases the flexibility. The external teeth expand in the building material, thus ensuring a high load-bearing capacity.
