The self-tapping metal fixing for gypsum plasterboard and gypsum fibreboard Cavity fixings Plasterboard fixing metal GKM BUILDING MATERIALS ▪ Gypsum fibreboard ▪ Gypsum plasterboard ADVANTAGES APPLICATIONS FUNCTIONING ▪ Due to its material properties, the GKM can be used in gypsum plasterboard and gypsum fibreboard, and can be used with the most wideranging 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. ▪ ▪ ▪ ▪ ▪ The GKM is suitable for prepositioned 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 5.0mm diameter. ▪ Pre-drill with a Ø8mm drill bit when using gypsum fibreboard and double-planked gypsum plasterboard. ▪ Not suitable for tiled plasterboard. http://www.fischerwerke.de/en/ - 16/07/2012 Pictures Lighting Electrical installations Fitting accessories 1
