ABSTRACT:
The invention concerns metal cages for set screw--cage systems intended to be mounted on a metal sheet accessible from only one of its faces. According to one aspect of the invention, the sidewalls 4 of the cage 3 of such a system are provided with an annular rib 16 projecting radially outwards, the external diameter of cage 3 at the rib 16 being slightly greater than the diameter of the hole 12 in which the cage is engaged, owing to which the cage is axially locked on the metal sheet. Dies are provided for the shaping of cage members. The invention finds application particularly in the fitting out of the bodies of vehicles.
