NUT - JAM (Doosan DWD490780)

A damaged jam nut can compromise threaded joint security in mechanical assemblies. During inspection, a loose or deformed jam nut may indicate improper torque or thread wear. The Doosan catalog reference for this aftermarket replacement part is DWD490780. This hardware nut type provides a plain mechanical function of locking another nut or bolt in place against vibration. A concrete generic failure consequence is that a missing or stripped jam nut can allow the primary fastener to loosen over time. The item ships at approximately 0.01 POUNDS.
