Milwaukee Spring
Model Number: 40-50-0018
The Milwaukee 40-50-0018 is a genuine OEM Spring for use in compatible Milwaukee tools. This is a precision-dimensioned coil spring that provides return force, retention force, or positional biasing at a specific mechanism interface within the tool. Milwaukee tools use springs throughout their internal mechanisms — in chuck release systems, mode selectors, safety interlocks, trigger return mechanisms, and gear engagement points — where a precisely calibrated spring force is required for correct mechanism operation. The spring's rate, free length, and wire diameter are all critical to correct function; an incorrect spring can cause mechanism failure even if it physically fits the space. A fatigued, broken, or set spring requires replacement with this exact part to restore correct spring-loaded function. Always order by exact catalog number to ensure the correct spring for the specific mechanism it serves.
Using a genuine Milwaukee OEM spring ensures the correct spring rate, free length, and wire diameter for the 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.
