WSHR FLT #10 .22 .50 .049 (Komatsu KO01641-10508)

KO01641-10508: A worn flat washer can allow fastener loosening under vibration, leading to component misalignment or detachment. This aftermarket replacement part references the Komatsu catalog number KO01641-10508. The washer is a flat, thin ring placed under a nut or bolt head to distribute load. Its plain mechanical function is to provide a smooth bearing surface and prevent galling. A generic failure consequence is that a missing or crushed washer can cause fastener pull-through or joint failure. Keeping a flat washer in sound condition helps maintain clamp load in bolted assemblies. Verify the serial number or application, then call (562) 693-7748.
