Improvements introduced in fixing nuts characterized in that they comprise a metal nut body having a plurality of intersecting lateral surfaces and an arcuate crown end portion extending between said lateral surfaces, said nut body defining a threaded central aperture with convolutions non-circular thread adjacent to the crown end portion of said nut body to interfere with a circumferential thread of coupling and circular thread convolutions adjacent the opposite end of said nut body to freely engage the coupling thread convolution; a plurality of series of indentations extending longitudinally in a plurality of lateral surfaces of said nut body, each series of indentations extending from an edge portion of an associated lateral surface of said nut body to the opposite edge portion of said nut body. The associated lateral surface of said nut body including indentations having a relatively small longitudinal extension adjacent said edge portions of the associated lateral surface and at least one indentation having a relatively large longitudinal extension adjacent to a central portion of the lateral surface associated, each of said indentations extending from the lateral surface associated with the crown portion of said nut body.
