Abstract
A receiving element which can be introduced into a borehole of at least one component includes a bolt presenting an outer surface that is approximately parallel and advantageously coaxial to a longitudinal axis of the bolt. The receiving element requires few materials and can therefore be produced at a low constructional cost while being provided with high dimensional stability and positioning accuracy. The bold includes an abrasion-resistant sintered material, and a metal tip provided on the front end of the shaft. The end part of the tip is engageable in a recess of the bolt, and there is a direct connection between the end part and the recess in the connection region on the front end of the bolt.
