Abstract

"Improvements introduced in the object of the main patent No. 277,721, granted on June 4, 1962, by:" Perfection in threaded metal fasteners ", characterized in that the driving tool comprises a central core and a series of radially prolonged fins from the same, the lateral faces of said fins are formed in such a way, in all their extension, that they are practically parallel to the central longitudinal axis of the insertion tool, and parallel to the corresponding lateral walls, practically vertical, of the grooves of the recess with which they are intended to be adjusted, and are further formed in such a way that, when the insertion tool is inserted inside the recess, a clearance not exceeding 0.025 is provided between the side faces of the fins and the side walls. mm necessary to allow insertion and removal of the insertion tool inside the recess; The introduction tool is further distinguished by the feature that its core, at intermediate positions between the circumferentially adjacent fins, is free of ribs to fit with the grooves of the V-section of the recess.
