A member for being joined to a mating member is provided. The member includes a number of drive sections that are engagable by a driver having corresponding driver sections. The rotation of the driver causes the member to be joined to the mating member. Each drive section can include a drive face body, a flat and a ramp. Each of them has an angular extent for desired contact with and engagement by the driver sections. The drive sections are integral with a drive support of the member. The drive sections can be located at a border section of the drive support. In one embodiment, the drive of the member is comprised of an inner drive and an outer drive. In another embodiment, the member is hollow. Different sized members can be joined to different mating members using the same driver. The drive is configured, particularly the ramp thereof, to substantially reduce unwanted removal of the member from the mating member.
