Ruuvien ja tulppien sarja Fischer GKM 12

The Fischer GKM 12 is a self-tapping metal fixing designed for fastening into gypsum plasterboard and gypsum fibreboard. Supplied complete with a countersunk chipboard screw, the metal anchor is suitable for pre-positioned installation and allows secure attachment of lights, electrical installations and interior accessories. For single-layer plasterboard no pre-drilling is required; for gypsum fibreboard and double-layer plasterboard a Ø 8 mm drill is recommended.

Advantages

The metal construction provides high shear and pull-out resistance in plasterboard. Delivered with matching countersunk chipboard screws, the GKM 12 enables quick, ready-to-use installation. Installation can be performed manually or with a cordless screwdriver, and the anchor sits flush with the board when correctly installed.

Suitable for

• Mounting interior lights
• Fixing electrical boxes and conduits
• Hanging bathroom and kitchen accessories
• Securing decorative elements to plasterboard

Recommendations

Check the load requirements and base material before installation. Use the appropriate drill for pre-drilling in fibreboard or double-planked boards and avoid overtightening the chipboard screw to preserve holding capacity.
