Plasterboard fixing metal GKM

The self-tapping metal fixing for gypsum plasterboard and gypsum fibreboard

The fixing is screwed in the pre-positioned installation into the Gypsum plasterboard and gypsum fibreboards flush to the surface. The sharp, self-tapping thread enables a secure, positive fit fixing. This achieves a high load-bearing capacity. The fischer GKM can hold wood, sheet metal and chipboard screws from 4 to 5 mm thickness as well as different hooks and eye screws. Consequently, it is universally suitable for fixing e.g. lights, electrical installations and fitting accessories securely and quickly.

Product Description

  • Due to its material properties, the GKM can be used in gypsum plasterboard and gypsum fibreboard, and can be used with the most wide-ranging screws, hooks and eye screws. This allows for a broad range of applications.
  • The sharp, self-tapping thread enables a secure, positive fit fixing. This achieves a high load-bearing capacity.
  • The cross-drive recess means that a standard screwdriver or bit can be used. No special setting tool is required.
  • The short fixing length means that only a small amount of space is required behind the board. As a result, the GKM can also be used in the case of unknown board thickness and cavity depth.
