A method for manufacturing a nut adapted to remove any paint layer covering a threaded shank as it is screwed onto this shank includes the pressing of a series of equiangularly-spaced radial recesses (9) on the inner surface of the nut before this inner surface is tapped. The recesses (9) extend axially from the end of the nut which feeds onto the threaded shank, and have a radial depth at least equal to the radial dimension of the thread of the nut. <IMAGE> |
