Milwaukee Disc Retaining Nut
Model Number: 49-40-0350
The Milwaukee 49-40-0350 is a genuine OEM Disc Retaining Nut for compatible Milwaukee angle grinders — the threaded nut that secures the grinding wheel, cut-off wheel, or sanding disc onto the grinder's spindle by threading onto the spindle and clamping the accessory between the nut face and the inner flange. The retaining nut is the final fastening component in the wheel mounting assembly — it must be properly tightened to the specified torque to achieve the clamping force that holds the wheel concentrically and securely on the spindle at the grinder's operating RPM. A damaged, deformed, or stripped retaining nut cannot apply the required clamping force for safe wheel retention — a wheel that is not properly retained on the spindle can loosen during operation, creating an extremely serious safety hazard from the high-velocity wheel ejection that results from inadequate spindle clamping force.
Using a genuine Milwaukee OEM retaining nut ensures the correct thread specification, clamping face diameter, and material specification for the specific Milwaukee angle grinder model — a retaining nut with incorrect thread pitch will not tighten properly on the spindle, and a nut with incorrect clamping face geometry may not provide adequate wheel support for safe high-speed operation. Always verify your specific Milwaukee angle grinder model number and serial number at milwaukeetool.com before ordering retaining nut service components.
