Abstract
Official abstract text for this publication.
An anchor bolt for an expansion anchor, and a method of producing the anchor bolt, is disclosed. The anchor bolt has an expansion body which is arranged coaxially with respect to an axis, where a circumferential surface of the expansion body has ribs and grooves in an alternating manner in a circumferential direction. Top surfaces of the ribs diverge from the axis in a direction along the axis. Bottom surfaces of the grooves converge in the direction of the axis.
