WASHER - LOCK (Hyster HY200511)

A damaged lock washer can allow a fastener to loosen under vibration, leading to component misalignment or failure. During assembly, a lock washer provides spring tension that resists rotational loosening. The Hyster catalog reference for this aftermarket replacement part is HY200511. This washer type creates a mechanical lock by deforming under torque, increasing friction between the fastener and mating surface. A loose fastener in a drivetrain or structural joint may cause noise, wear, or sudden disassembly. This item ships at approximately 0.042 pounds.
