Abstract
When it comes to an expansion plug () including an anchor bolt () with an expansion element () on a first end section () of the anchor bolt () having a longitudinal axis (), preferably also including at least one force-applier () on the anchor bolt () in order to hold loads, and also including an expansion sleeve () surrounding the anchor bolt (), the objective is to avoid an axial movement of the expansion sleeve (), especially in the case of a drilled hole diameter in the lower tolerance range or in the case of a hollow space. The expansion plug () has at least one eccentric geometry, so that an expansion of the expansion sleeve () can be achieved by a rotational movement of the anchor bolt (), especially around the longitudinal axis () as the axis of rotation ().
