Milwaukee Detent Spring
Model Number: 40-50-8320
The Milwaukee 40-50-8320 is a genuine OEM Detent Spring for compatible Milwaukee power tools — a small precision spring that provides the spring-loaded force for a detent ball or detent pin retention mechanism within the tool's body. Detent springs in Milwaukee tools serve the specific retention function of the detent mechanism they are part of — providing the calibrated spring tension that keeps a detent ball seated in its notch or groove to hold a mechanism component, accessory, or adjustment position in the selected position until deliberate force overcomes the detent resistance for intentional release or repositioning. When a detent spring fatigues, breaks, or loses its spring force from the repeated compression cycles of the tool's detent mechanism operation, the detent retention force decreases below the minimum needed to reliably hold the mechanism in position — allowing unintended release, position change, or accessory ejection during tool operation.
Using a genuine Milwaukee OEM detent spring ensures the correct spring rate, wire diameter, coil count, and free length for the specific detent mechanism the spring serves — a spring with incorrect spring rate would either not provide adequate detent retention force or would require excessive release force that makes the mechanism difficult to operate intentionally. Always verify your specific Milwaukee tool model number and serial number at milwaukeetool.com before ordering detent spring service components, as spring specifications are unique to each tool model and mechanism.
