Item Details

  • OEM 1/4-20 Left-Hand Threaded Socket Head Chuck Retaining Screw. This component secures keyed or keyless chucks to the drive spindle of reversing rotary power tools. It functions to counteract rotational inertia and reverse-torque forces, maintaining a mechanical lock between the chuck assembly and spindle during operation.

Features

  • Left-Hand Thread Geometry: Tightens during forward spindle rotation to prevent backing out
  • Internal Hex Socket Drive: Allows torque transmission in restricted chuck bores without cam-out
  • Concentric Seating Face: Machined perpendicular to thread axis to prevent spindle oscillation and runout
  • Alloy Steel Construction: Quenched and tempered for fatigue resistance and high tensile strength
  • Black Oxide Finish: Provides lubrication during torque application and atmospheric oxidation resistance
  • OEM Specification: Matches original thread direction and dimensional tolerances for Milwaukee tool spindles
  • Counter-Intuitive Extraction: Requires clockwise rotation for removal due to left-hand thread orientation
