Milwaukee Anvil Spring
Model Number: 40-50-0057
The Milwaukee 40-50-0057 is a genuine OEM Anvil Spring for use in compatible Milwaukee impact drivers and impact wrenches. The anvil spring is the return spring in the impact mechanism that acts on the anvil — providing the restoring force that returns the anvil to its reset position after each impact stroke, ensuring the hammer can re-engage for the next blow. Correct anvil spring force is critical for consistent impact cycling; a weakened or broken spring causes sluggish impact cycling, reduced blow rate, or complete loss of impact action. A fatigued, broken, or permanently set anvil spring that can no longer provide its specified return force requires replacement to restore full, consistent impact performance.
Using a genuine Milwaukee OEM anvil spring ensures the correct spring rate and free length for the impact mechanism it serves. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct spring for your specific unit.
