This sheet metal nut secures M6 fasteners to the chassis of the host tractor. It is a stamped steel clip-nut that engages the screw thread and locks into a chassis panel hole, providing a threaded anchor where direct access to the opposite side is restricted. The nut's spring-tension grip holds it in position during assembly and resists vibration loosening in service. As an original AGCO part, its thread profile and clip geometry match the chassis panel thickness and hole pattern of the original assembly, so no additional washers or retainers are needed. Replace the nut if the clip has lost its tension or the threads are stripped; a loose nut can allow the fastened component to shift, leading to misalignment or secondary damage.
