Abstract
Improvements in the manufacture of non-loosening threaded fasteners comprising a rod with head and thread that has a blocking zone made up of contiguous turns deviated from its normal pitch, characterized by the fact that the blocking zone is constituted by arranging at least a part of a first gyrus or truncated turn (26) whose free flank (92) is oriented relative to a radial plane (102) of the fastener (20) at an angle less than half the normal angle of the thread, and whose flank (94) that receives the insertion effort is located at the half of the angle of the thread also in relation to the radial plane (102), as well as having a second turn (30) less truncated than the contiguous and first mentioned turn (26) .
