Milwaukee Flat Spring
Model Number: 40-50-8525
The Milwaukee 40-50-8525 is a genuine OEM Flat Spring for use in compatible Milwaukee tools. Flat springs — also called leaf springs or flat-stock springs — are formed from flat spring steel strip and use the elastic deflection of the flat section to generate a restoring or contact force. Unlike coil springs, flat springs exert their force through bending rather than compression or extension, making them well suited for brush holder retention, contact retention, detent engagement, latch mechanisms, and low-profile applications where a coil spring cannot be accommodated. Each flat spring is formed to a specific geometry and thickness that determines its spring rate and force output at a given deflection. A broken, permanently bent, or fatigued flat spring that can no longer provide the correct contact or return force requires replacement to restore proper mechanism function.
Using a genuine Milwaukee OEM flat spring ensures the correct strip thickness, geometry, and temper specification for the mechanism it serves. Non-OEM flat springs may not match the original force characteristics, leading to improper mechanism function. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct flat spring for your specific unit.
