A mounting device for fastening a printed circuit board onto a carrier is disclosed. The mounting device comprises at least one bolt that can be screwed onto the printed circuit board, having at least one fastening wing, wherein the fastening wing has at least one interlocking component. Furthermore, the mounting device comprises at least one bolt receiver that is or can be integrated in the carrier. The bolt is or can be disposed in the bolt receiver such that it can be displaced in the direction of a displacement axis that is oriented substantially perpendicular to a main extension plane of the printed circuit board. The bolt receiver comprises at least one groove for receiving at least one subsection of the fastening wing having the interlocking component. The interlocking component is designed to interlock in the groove when the bolt disposed in the bolt receiver is subjected to a predetermined torque.
