The nut with code K 11833 is specifically manufactured to secure stud bolt K 11823 in the ZV40/48 engine configuration. Designed to resist loosening from vibration and thermal stress, this high-strength fastener maintains the structural connection of critical engine parts, such as casings, manifolds, or covers. Precision-machined threading ensures uniform torque distribution and long-term stability, which is crucial for preserving engine alignment and minimizing mechanical wear. The nut’s reliability directly supports the integrity and longevity of the engine assembly under heavy-duty use.
