LOCKNUT - NYLON (Komatsu KO01584-00805)

KO01584-00805: A damaged locknut can allow threaded fasteners to loosen under vibration, leading to mechanical misalignment or component separation. The locknut type uses a nylon insert that deforms against the bolt threads to resist backing off. This aftermarket replacement part references the Komatsu catalog number KO01584-00805. The nylon insert provides a prevailing torque that maintains clamping force without additional locking devices. A common failure consequence is gradual loosening that permits joint movement and eventual part detachment. Keeping a locknut in sound condition helps preserve bolted joint integrity in equipment assemblies. Verify the serial number or application, then call (562) 693-7748.
