The fischer wall screw MR is an anchor sleeve with an internal expansion pin made from zinc-plated steel. The wall screw is ideal for non-approval-relevant anchorings of handrails, gratings, and garden gates, for example, in non-cracked concrete and natural stone with a dense structure. The wall screw MR is set in a pre-positioned and push-through installation. The anchor sleeve is hammered into the drill hole without an expansion pin. The expansion pin is hammered in afterwards. This expands and braces itself against the drill hole wall.
