Multiple split, internally threaded anchors made of brass. The specially ribbed surface prevents rotation in the drilled hole. The anchor designation indicates the required screw diameter. The fastening can be loosened and tightened without releasing the anchor. No setting tool is required. Corrosion-resistant fastening for indoor and outdoor use. The screw length corresponds to the anchor length plus the thickness of the fixture. Suitable for all screws and threaded rods with metric threads. If necessary, the brass anchors can be easily pre-expanded by screwing in the threaded screw. Features through-mounting and insert-mounting. Ideal for spacer mountings in combination with threaded rods.
