| Product details | - The fischer GKM drywall fastener is made of metal. For pre-positioned installation, it is screwed in by hand or with a cordless screwdriver until it is flush with the drywall surface. Pre-drilling is not necessary for single-layer drywall. For gypsum fiberboard or double-layer drywall, pre-drilling with an 8mm drill is required. The GKM accepts 4 to 5mm wood, self-tapping, and chipboard screws, as well as various hooks and eyelets, making it suitable for quickly and securely mounting lights, electrical systems, and interior accessories.
-
- Suitable for drywall and gypsum fiberboard and compatible with a wide range of screws, hooks, and eyelets for a wide range of applications.
- The Phillips recess allows the use of standard screwdrivers or bits, eliminating the need for special adjustment tools.
- The sharp, self-tapping thread ensures a secure, positive fixation with high load-bearing capacity.
- The short fixing length requires minimal space behind the panel, making the GKM suitable for unknown panel thicknesses and cavity depths.
