Screw with radius point - has enveloping surface of radius end being tangential to end of cylindrical body of screw

摘要

The screw with a radius point possesses a cylindrical body (13) where the threaded section extends over this section and the radius point (15) with a constant depth of thread. The enveloping surface (s15) of the radius end (15) is tangential to the end (16) of the cylindrical body (13) of the screw and that the geometrical place of a centre of curvature (O) the generated curve of the point is situated in the plane of the cross section of the end (16) of the body of the screw. Use/Advantage - An auto-driven screw with radius point for fixing in a threaded nut where the two are not originally aligned.
