Abstract
A screw for the electrical connection of a cable terminal to a railway track or the like comprises a base body having an elongated shank having a longitudinal axis, a strike head connected with a first end of the shank, and threads for the removable connection of a strike organ or nut with a second end of the shank opposite said first end. The screw further comprises a support element manufactured separately from the base body and associated to the strike head so as to form a stroke that defines a cavity turned towards the second end of the shank. The screw is pre-assembled and the support element is substantially irreversibly connected to the base body.
