The self-tapping metal fixing for gypsum plasterboard and gypsum fibreboard
Plasterboard fixing metal GKM
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.
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.
Application and approval
You can find detailed information on building materials in the approval document.
The GKM is suitable for pre-positioned installation.
The self-tapping metal fixing GKM taps itself into the plasterboard with a positive fit.
Flush installation in the board building material. Overtightening the fixing should be avoided. Therefore, the installation torque should be limited when using a battery operated screwdriver.
Adapted for wood, self-tapping and chipboard screws of 4.0 to 5.0 mm diameter.
Pre-drill with a Ø 8 mm drill bit when using gypsum fibreboard and double-planked gypsum plasterboard.
