The disclosure relates to a method for producing load-indicating connection components. A connection element (10) and a piezoelectric ultrasonic transducer (20) are provided and interconnected. The method comprises forming a layer structure on the surface (14) of the connection element (10). The layer structure comprises, in this order, proceeding from the surface (14) of the connection element (10): a first solder layer (16); a reactive layer (30); a second solder layer (22); and the piezoelectric ultrasonic transducer (20). The reactive layer (30) is designed for an exothermic reaction by activation with heat, with electromagnetic radiation or with electric current. Subsequently, the piezoelectric ultrasonic transducer (20) is pressed toward the connection element (10) in order to produce a specified contact pressure, and the reactive layer (30) is activated. The disclosure also relates to a load-indicating connection component of this type.
