Fischer GKM Self-Drilling Drywall Anchor Set 31 mm, Nylon, Zinc-Plated Screws, 50 Pieces 090917

For electricians and drywall installers securing light fixtures, cable conduits, or junction boxes onto plasterboard, the Fischer GKM self-drilling anchor set offers a fast, tool-free installation. The nylon anchor cuts its own thread directly into the panel, eliminating the need for pre-drilling or a special setting tool. Each zinc-plated steel screw drives flush, creating a clean, secure hold in gypsum fibreboards and plasterboard from 9.5 mm thick.
