Sada šroubů a hmoždinek Fischer 519782

The fischer cavity metal anchor HM-S is a versatile cavity fixing with a metric screw designed for board building materials such as gypsum fibre board and plasterboard. It is set in a pre-positioned installation using the fischer installation pliers HM-Z 1 or alternatively by screwdriver or cordless screwdriver. When set, the anchor is pulled into the cavity and its expanding arms open and press against the reverse side of the board to create a secure connection. The HM-S is suitable for fixing lights, towel rails and curtain rails.

Advantages

The HM-S range covers board thicknesses from 3 to 50 mm, making it adaptable to many applications. Its metric internal thread allows attachments to be removed and refitted multiple times for flexible use. Expanding arms provide a large bearing surface for high load capacity, while peripheral claws bite into the board to prevent rotation and ensure a reliable installation.

Suitable for

• Fixing lights to drywall or gypsum fibre board
• Mounting towel rails on board building materials
• Installing curtain rails in hollow walls
• General fastening of fixtures to plasterboard

How to use

Drill the correct diameter hole in the board material, insert the HM-S anchor into the pre-positioned hole, and set it by pulling the anchor into the cavity with the fischer installation pliers HM-Z 1 or by tightening with a screwdriver/cordless screwdriver until the expanding arms deploy and press against the reverse side of the board. Once set, attach the fixture using a compatible metric screw and tighten to the required torque without over-tightening to avoid damaging the board.

Recommendations

Use anchors sized to match the board thickness and the load. For repeated removal and refitting of fixtures choose the HM-S variant with the appropriate metric thread. When installing heavier items, verify the load capacity for the specific board type and consider multiple anchors or supplementary support.
