WSHR FLT .31 .38 .88 .083 (Komatsu KO01640-30816)

KO01640-30816: A worn flat washer can allow fastener loosening under vibration, leading to component misalignment or detachment. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO01640-30816. The washer provides a smooth bearing surface between a fastener head and the mating part. Its flat profile distributes clamping load evenly to prevent surface damage. In a typical application, a missing or undersized washer may cause the fastener to embed into softer material, reducing joint integrity. Verify the serial number or application, then call (562) 693-7748. The part is a flat washer with nominal dimensions of 0.31-inch inner diameter, 0.38-inch outer diameter, and 0.083-inch thickness.
