ABSTRACT:
The invention relates to a receiving element comprising a bolt with an external surface that is essentially parallel to and in particular coaxial with a longitudinal axis. Said bolt can be introduced into a bore of at least one component, preferably at least two components in order to fix and/or align said component(s) for subsequent machining. The aim of the invention is to develop the receiving element whilst maintaining a simple construction in order to ensure a high dimensional stability and positioning precision over a long service life. To achieve this, the bolt comprises at least two recesses containing orifices in the vicinity of its external surface, said recesses containing pins, which consist of or comprise wear-resistant sintered material, extend through said orifices in a partial radial manner and project beyond the external surface with a predefined overhang.
