Which term corresponds to the concept of 'bolt' in German?

The term 'bolt' in German is correctly translated as 'Bolzen.' This term specifically refers to a type of fastener that is typically used to hold objects together by being inserted through aligned holes and secured with a nut. In mechanical and structural contexts, bolts are essential components for ensuring stability and strength in various constructions.

The other terms listed do not refer to the concept of 'bolt.' For example, 'Schutzschalter' translates to 'circuit breaker,' which is an electrical device used to protect circuits from overload or short circuit conditions. 'Kronenmutter,' on the other hand, means 'crown nut,' which is a specific type of nut that has prongs or fins and is used in various engineering applications but is not a direct equivalent to bolt. Finally, 'Verbrauchsmaterial' translates to 'consumable material' and refers to items that are used up and need to be replaced, which is not relevant to the concept of a bolt. Thus, 'Bolzen' is accurately reflective of the meaning of 'bolt' in the context of fasteners.
