NUT - TOP LOCK 3/8-24 (Bobcat BC86D-6)

BC86D-6: A damaged top lock nut can lead to fastener loosening under vibration. During assembly, a 3/8-24 thread size nut provides secure clamping force. Keeping a top lock nut in sound condition helps maintain joint integrity in mechanical connections. This aftermarket replacement part references Bobcat as the OE maker and carries the cross-reference number BC86D-6. The nut type relies on a deformed thread or nylon insert to resist backing off. A common failure consequence is gradual loosening, which may allow connected components to separate. Verify the serial number or application, then call (562) 693-7748.
