  • Patent number: 5265503
    Abstract: A lug nut and socket wherein the socket and nut engage only selected point surfaces. In one aspect of the invention the socket has a decreased number of point surfaces. In another aspect of the invention, the lug nut has a decreased number of point surfaces. In another aspect of the present invention the socket points surfaces include point pins which are positioned to engage a pair of diametrically opposed point surfaces on the lug nut. The point pins are removably inserted into point pin wells extending into the lug nut socket. In another aspect of the present invention a retainer ring is provided to prevent the removable point pins from falling out during operation or handling, or otherwise being unintentionally removed. In another aspect of the present invention, the socket bore which engages a lug nut during operation is deliberately oversized to allow for considerable play between the lug nut and the socket.

  • Patent number: 5174702
    Abstract: A lug nut retainer that holds a lug nut in position proximate to a wheel lug hole to accept a stud extended through the wheel lug hole and for resiliently urges the lug nut onto the stud while allowing the lug nut to rotate to screw onto and off the stud. A resilient retaining clip is mounted onto the wheel to hold the lug nut in position near the wheel lug hole and to resiliently urge the lug nut towards the wheel lug hole. The retaining clip is fastened to the wheel lug hole by inserting an arm of the clip through two holes provided in the wheel. As an additional feature, a limit clip is provided that limits the motion of the retaining clip to decrease the likelihood that the retaining clip may be bent or damaged while allowing the retaining clip to be positioned on a nut. The lug nut is provided with a socket stop ring around which the retaining clip is positioned. The stop ring keeps the socket from rubbing against the retaining clip.
