Removal and installation of the attachment can be repeated without reducing load-carrying properties. This increases flexibility.
High load capacity due to the large supporting surface provided by the expansion arms.
Turning lock for convenient assembly: Claws on the edge of the fixing secure the fixing in board building material.
Suitable for pre-positioned installation.
Complete with screw.
Your advantages / Product description
The versatile metal cavity fixing with metric screws
Due to the extensive range, the HM is suitable for board building materials with a thickness of 3-50 mm and thus suitable for a number of different applications.
The metric internal thread allows the attachment to be removed and refitted several times, thus offering the best possible flexibility.
The HM's expanding arms ensure a large supporting surface, thus allowing a high load-bearing capacity.
The claws around the edge of the fixing penetrate the board building material, preventing the fixing from rotating, thus ensuring a secure installation.
The fischer cavity metal anchor HM-S is a versatile cavity fixing with a metric screw for all panel building materials. The fixing is set with the fischer installation pliers HM-Z 1 in the pre-positioned installation. The fixing is pulled in the cavity against the board building material with the pliers. In this case, the expanding arms swing open and press onto the reverse side of the board. Alternatively, assembly can be carried out either with a screwdriver or a cordless screwdriver. The cavity metal anchor HM-S is suitable for fixing lights, towel rails, and curtain rails.

You can find detailed information on building materials in the approval document.
The metal cavity fixing HM is suitable for pre-positioned installation.
The fixing should be selected based on the thickness of the board building material, to allow the very best expansion in the cavity.
During installation, the expanding arms swing open and press onto the reverse side of the board.
The HM can be installed using installation pliers. If using a battery operated screwdriver or screwdriver for installation, the pre-assembled screws must be removed first. When screwing in and expanding the fixing, the attachment, or a max. 6 mm plate, needs to be used as a turning stop.
