  • Patent number: 7137213
    Abstract: A shoe stud and receptacle combination for specifically oriented studs, the shoe stud (1) including a ground-engaging part (4). The stud (1) and receptacle (2) are adapted to be secured together by a multi-start threaded connection comprising a screw-threaded spigot (5) on one of the components adapted to be inserted with rotation into a screw-threaded socket on the other component. A locking means (7) of the components is arranged to become interengaged at least when the spigot (5) is fully inserted into the socket (22) to resist unscrewing of the components. The locking means (7) comprises at least one locking assembly (8), the arrangement is such that the relative number and/or position of the threads of the threaded connection and the locking assemblies (8) determine the initial and final positions of the stud (1) relative to the receptacle (2).
