US Patent 7722060 Truck assembly for wheeled recreational device

A truck assembly is used in a wheeled recreational device including a base plate and hanger. The base plate defines a plurality of mounting holes adapted for receiving respective threaded bolts, and further defines a corresponding plurality of fastener retention regions surrounding respective mounting holes. Each fastener retention region includes point-engaging structure adapted for engaging at least two points of a multi-point threaded nut, such that the point-engaging structure substantially prevents rotation of the threaded nut upon mating attachment of a corresponding threaded bolt. The hanger resides adjacent to the base plate, and includes a wheel axle adapted for carrying at least one wheel of the recreational device.
