NUT - HEX SLOT (Komatsu KO01599-01817)

KO01599-01817: A damaged hex slot nut can compromise the security of a bolted joint, leading to loosening under vibration. During assembly, this nut type uses a slot across its top to accept a cotter pin or locking wire for positive retention. The aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO01599-01817. Its general function is to fasten components by threading onto a bolt or stud, with the slot providing a mechanical lock against rotation. A common failure consequence is that a worn or stripped nut may allow the joint to separate, causing misalignment or component detachment. Keeping a hex slot nut in sound condition helps maintain clamping force in applications where safety wiring is required. Verify the serial number or application, then call (562) 693-7748.
