Thread-producing nut, blank for the fabrication of said nut, and bolted joint composed of said nut and a bolt

A thread-foaming nut for positive, nonpositive and releasable connection to a stud or bolt, the thread-forming nut comprising:

• a core hole provided with load-bearing thread turns and the thread turns are disposed on a peripheral surface of the core hole in a peripheral direction, wherein the thread turns, as regarded in the peripheral direction, partially comprise perfectly formed thread turns, wherein between perfectly formed regions of the thread turns there are provided free spaces comprising in terms of height imperfectly formed thread turns and wherein the load-bearing thread turns in the core hole lie at their roots on a minor thread diameter (Dn) and at their crests on a major thread diameter (D1), wherein the thread turns comprise, at least in part, free spaces that widen the core hole from the major thread diameter (Dn) towards the minor thread diameter (D1), and wherein the free spaces terminate at a distance from the minor thread diameter (D1) on an outer circle diameter (Da).
