Chuck Retention Screw (Left-Hand Thread)
This screw utilizes a reverse (left-hand) thread to counteract the rotational inertia of the chuck during braking and reverse operation. If this screw is missing or loose, the chuck will spin off the spindle or wobble during use. Replacing this screw and applying appropriate torque prevents the assembly from decoupling from the motor spindle.

1/2-in Keyless Ratcheting Chuck
Internal wear on the ratcheting teeth or the jaw guide springs prevents the chuck from 'locking' the bit in place. The aggressive electronic braking on 20V models often causes standard friction-based chucks to loosen; this ratcheting version is the specific assembly designed to maintain jaw pressure under high-inertia stops.
