Milwaukee Spring Washer
Model Number: 05-90-0225
The Milwaukee 05-90-0225 is a genuine OEM Spring Washer for use in compatible Milwaukee tools. Spring washers — also commonly known as split lock washers — are hardened, split-ring washers that are placed under a bolt head or nut before tightening. When the fastener is tightened, the washer compresses and stores spring energy against both the fastener bearing surface and the joint face, creating a constant load that resists the fastener backing out or loosening under vibration, impact, and dynamic operating loads. This makes spring washers a common addition to fastener locations throughout tool assemblies where sustained vibration during operation creates a risk of fastener loosening over time. A flattened, cracked, or missing spring washer that no longer provides the correct spring load at the fastener interface requires replacement to restore proper vibration resistance at the joint.
Using a genuine Milwaukee OEM spring washer ensures the correct inner diameter, outer diameter, thickness, and spring rate for the fastener and housing interface it serves. Non-OEM spring washers may not match the original dimensional specification or material hardness, leading to insufficient spring load or improper fit under the fastener head. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct spring washer for your specific unit.
