The removal and installation of the fixed element can be repeated without reducing the load-bearing capacity, increasing flexibility. High load-bearing capacity due to the large support surface provided by the expansion arms. Rotation prevention for easy installation: the slots on the support washer secure fastening to thin-walled construction materials. The product is suitable for pre-installation and includes a metric screw.

Installation instructions

• The HM metal fixing is suitable for pre-installation.
• The appropriate fixing should be selected according to the thickness of the thin-walled construction material, for optimal expansion.
• During installation, the expanding arms open and press against the back side of the plate.
• The HM can be installed using the HM Z expansion tool.
• If a screwdriver or cordless screwdriver is used, the pre-assembled screw must first be removed and a 6 mm thick element inserted, to act as a screw-in brake.
