Abstract
A lug nut removal and storage system, for removing lug nuts from lug bolts, comprising a tube. The tube has a tube exterior, a proximal end, a distal end, and a proximal distal axis. A channel extends into the distal end wherein the lug nuts are stored. A plurality of ball bearings are disposed around the channel near the distal end. The ball bearings in ball bearing bores transverse to the channel, the ball bearings moving in the ball bearing bores to narrow and widen the channel. A spring clip selectively restricts the outward movement of the ball bearings, so that the ball bearings will maintain the lug nuts in the channel, and releases the ball bearings so that the ball bearings will widen the channel sufficient to release the lug nuts from the channel. A main spring extends in the channel from the proximal end toward the distal end, the main spring biasing the lug nuts against the ball bearings.
