Abstract

Externally threaded fixing screw of predominantly tightening with a threaded shank, the turns of the shank thread extending their ridges in an imaginary straight cylinder, whose cylindrical surface passes through said crests, characterized by an off-center segment of substantial arched length in each of a plurality of turns of said thread and each of said segments being off-center from the remainder of the turn in which it is located, said off-center segments being positioned to form a group of vertically aligned offset segments of a substantial arcuate length the crests of which extend in said cylindrical imaginary surface, said group being positioned between the ends of the threaded part of said rod, the thread segments being offset from at least one pair of contiguous off-center segments of the group offset from each other and extending all of the aforesaid decentered segments of said screw are said to be in the same helix angle as the helix angle of the rest of said thread.
