摘要

Disclosed is a bolt ( 10 ) that can be pressed into a metal sheet in a torsion-proof and ejection-proof manner and comprises a head ( 12 ). The side of the head ( 12 ) facing the metal sheet after being inserted is provided with radially arranged webs ( 22 ) which are pressed in when being inserted into the metal sheet. A cylindrical winding support ( 14 ) is disposed in the center of the head ( 12 ). Said winding support ( 14 ) extends through the metal sheet and protrudes on the other side thereof while being provided with a circumferential annular groove ( 20 ) near the side of the head ( 12 ) that faces the metal sheet in the set state. The sheet metal material that is displaced during the setting process can be pressed into said annular groove ( 20 ). All or part of the side of the head ( 12 ) facing the metal sheet is provided with a rubber-elastic sealing material ( 110 ).
