WASHER - SPLIT LOCK 1/4 (Clark CL3291190)

A damaged split lock washer can compromise fastener tension and lead to loosening under vibration. During assembly, this washer type provides a spring-like action that resists rotational loosening. The catalog reference is Clark part number CL3291190, offered as an aftermarket replacement. Its general function is to prevent nuts and bolts from backing out due to dynamic loads. A common failure consequence is that a worn or missing lock washer allows joints to separate, causing misalignment or component detachment. Keeping a split lock washer in sound condition helps maintain clamping force in threaded connections. Verify the serial number or application, then call (562) 693-7748.
