It is a hardened steel nut (SAE J995 Grade 8) with a phosphate and oil coating, designed as part of Cat’s matched bolt-nut-washer system to deliver consistent clamp loads on heavy equipment. You would replace it if the threads are stripped, corroded, or during a scheduled overhaul to maintain proper torque and safety.
