NUT - JAM LOCK PLASTIC (Bobcat BC66D12)

BC66D12: A damaged jam lock nut can allow fastened components to loosen under vibration. During inspection, a plastic jam lock nut may show cracking or deformation that reduces its locking ability. The nut's plain mechanical function is to resist backing off by deforming slightly when torqued against a standard nut. A concrete generic failure consequence is that a compromised jam lock nut can lead to joint separation and equipment downtime. Keeping a jam lock nut in sound condition helps maintain secure fastening in threaded assemblies. This aftermarket replacement part references Bobcat catalog number BC66D12.
