Fischer Spreizdübel SX

Universal screws countersunk head 4.5 x 35 mm, cross recess. Functionality: The GKM is suitable for push-fit installation. The GKM self-drilling metal plug cuts into the plasterboard with a positive fit. Installation flush with the surface of the board material. Avoid over-tightening the plug. Therefore, the insertion torque must be limited when using cordless screwdrivers. Adapted to wood, sheet metal and chipboard screws from Ø 4.0 to 5.0 mm. Pre-drill in gypsum fibreboard and double planked plasterboard with Ø 8 mm drill bit. Not suitable for tiled plasterboard. Applications: Pictures, lights, electrical installations, furnishing accessories. Advantages: Due to its material properties, the GKM can be used in plasterboard and gypsum fibreboard and can be used with a wide variety of screws, hooks and eyelets. This opens up a wide range of applications. The sharp, self-drilling thread enables secure, form-fit fastening. This achieves a high load-bearing capacity. The cross recess drive means that a standard screwdriver or bit can be used. No special setting tool is required.
