Milwaukee Compression Spring
Model Number: 40-50-1330
The Milwaukee 40-50-1330 is a genuine OEM Compression Spring for use in compatible Milwaukee tools. Compression springs are helical springs designed to resist compressive axial loads — storing energy when compressed and releasing it as a restoring force when the compressive load is removed. They are used throughout Milwaukee tool assemblies to provide return force on depressed buttons and levers, pre-load bearings and clutch mechanisms, maintain detent engagement in selector mechanisms, and drive ejector and release functions. Each compression spring is manufactured to precise wire diameter, coil count, free length, and spring rate specifications for the mechanism it serves. A broken, fatigued, or permanently set compression spring that can no longer provide its specified return force requires replacement to restore correct mechanism function.
Using a genuine Milwaukee OEM compression spring ensures the correct wire diameter, free length, and spring rate for the compressed interface 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.
