Milwaukee Set Screw
Model Number: 05-81-0020
The Milwaukee 05-81-0020 is a genuine OEM Set Screw for use in compatible Milwaukee tools. Unlike conventional screws, a set screw is a headless fastener that is threaded entirely along its length and is driven fully into a tapped hole until it is flush with or below the surrounding surface. Set screws are used to lock rotating components — such as gears, pulleys, collars, and cams — onto shafts by applying direct clamping or point contact force against the shaft surface, preventing the component from rotating or sliding axially during operation. Because the set screw sits completely below the surface with no protruding head, it does not interfere with adjacent moving parts or housing clearances. A loose, stripped, or missing set screw allows the component it secures to rotate or shift on the shaft — resulting in lost motion, irregular performance, or component damage — requiring replacement to restore secure shaft-to-component engagement.
Using a genuine Milwaukee OEM set screw ensures the correct thread specification, length, point style, and drive recess for the application it serves. Non-OEM set screws may not match the original thread class or point geometry, leading to inadequate holding force against the shaft or improper seating in the tapped hole. Always verify your catalog number and serial number on Milwaukee's website before ordering to confirm this is the correct set screw for your specific unit.
