NUT - JAM (JLG JL1122477DTZ)

A damaged jam nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, this aftermarket replacement part functions as a secondary lock nut, threaded against the primary nut to prevent unintended rotation. The catalog reference is JLG, with cross-reference part number JL1122477DTZ. This nut type provides a plain mechanical function by increasing friction on the fastener threads. A common failure consequence is gradual fastener loosening, which may allow connected components to shift or separate. The item ships at approximately 0.01 POUNDS.
