WSHR FLT .31 .38 .88 .083 (Komatsu KO01601-00825)

A worn flat washer can allow fastener loosening under vibration, leading to component misalignment or detachment. This aftermarket replacement part references Komatsu catalog number KO01601-00825. The washer is a thin, ring-shaped component placed between a fastener head and a surface. Its primary mechanical function is to distribute the clamping load evenly across the mating area. A common failure consequence is that a crushed or missing washer reduces preload, causing the fastener to back out during operation. Keeping a flat washer in sound condition helps maintain consistent joint integrity in assembled equipment. Verify the serial number or application, then call (562) 693-7748.
