Abstract

A metallic nut 5, of the kind which provides automatic limitation of the tension to which it can be tightened, includes a first portion 1 with internal threading 4 coupled by an annular shearing zone 3, having a cross section which is small relative to the useful cross section of the nut, to a coaxial second portion 2 having a non-threaded internal bore 6, and flats 21 for cooperating with a tightening tool, a continuous electrically-insulating casing 31 extending externally from the first portion 1 to the second portion 2. The casing 31 is adherent to the two portions 1, 2 and may retain them adjacent to each other after they have been separated by shearing; alternatively the casing is broken or sheared at an annular zone thereof. The internal bore 6 may have internal fiats, or the flats 21 may project beyond the casing 31. <IMAGE>
