The fischer GKM 27 plasterboard dowel is made of metal. The dowel is screwed into the plasterboard flush with the surface using a cordless screwdriver or by hand. No pre-drilling is necessary for single-planked plasterboard. For gypsum fiberboard and double-planked plasterboard, pre-drill with a Ø 8 mm drill.The fischer GKM 12 is supplied complete with a countersunk chipboard screw. This makes it universally suitable for attaching lights, electrical installations and furnishing accessories quickly and safely.
No drilling necessary in single-planked plasterboard. This saves time.
High load-bearing capacity thanks to form-fitting fastening.
Little space required behind the panel thanks to short dowel length.
