The fischer expansion plug M-S is made of high-quality nylon for screws with a metric thread. The special fixing can be set in pre-positioned and in time-saving push-through installation. When screwing in the screw, the M-S expands and anchors itself in the drill hole. The fischer expansion plug M-S is ideal for fixing handles, folding shutters, or downpipes in concrete, aerated concrete, solid gypsum panels, and in all other solid and hollow building materials.
