Multi-split internally threaded anchor made of brass. The special knurled surface prevents rotation in the drill hole. The dowel designation indicates the required screw diameter. The attachment can be loosened and tightened without loosening the plug. No setting tool is required. It is a corrosion-resistant fixing suitable for both interior and exterior use. Screw length Ls equals anchor length plus attachment thickness. It is suitable for all screws and threaded rods with metric thread. If necessary, slightly pre-spread brass anchors by screwing in the threaded screw. It allows for through-fixing and pre-fixing, making it ideal for spacer assemblies in combination with threaded rods.
