A DIN 557 Square Caged Nut is a specialized captive fastener that integrates a regular-pattern square nut (DIN 557) into a flexible spring-steel cage. This assembly allows the nut to be "snapped" into square pre-punched holes in thin materials, providing a secure, replaceable threaded mounting point.
