Milwaukee Tool Retaining Washer
Model Number: 45-88-0601
The Milwaukee 45-88-0601 is a genuine OEM Tool Retaining Washer for compatible Milwaukee power tools — a precision-stamped or machined washer component that provides the axial retention function for the tool accessory or chuck component at the tool's output spindle or accessory mounting interface. Tool retaining washers lock or capture the tool accessory, chuck, or related component in its correct axial position on the spindle, preventing the component from backing off the spindle under the axial forces generated during tool operation. When a retaining washer deforms, fractures, or wears to the point where it no longer provides adequate retention force, the component it retains can shift axially during operation — potentially loosening, vibrating, or in severe cases separating from the spindle during use. The retaining washer must be replaced immediately when its retention function is compromised.
Using a genuine Milwaukee OEM retaining washer ensures the correct outer diameter, inner bore, thickness, and material specification for the specific spindle diameter and accessory retention force required in the tool application — washers with incorrect dimensions either provide inadequate retention force or cannot be installed in the space available at the spindle end. Always verify your specific Milwaukee tool's model number and serial number at milwaukeetool.com before ordering retaining hardware, as washer specifications are unique to each tool model and spindle configuration.
