Fischer GKM sada samovŕtacích hmoždiniek pre sadrokartón 31 mm, nylon, pozinkované skrutky, 50 ks 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.
