    摘要： A non-permanent, corrosion-resistant joining device, which comprises, on at least a part (15) of a surface of an element of a joint (11, 12) facing a structural element (20) made of at least one composite material, at least a film of prepreg E-Glass and epoxy resin (13, 113). The joining device can be a screw (11), a nut or a washer (12).
    A method for the production of a non-permanent, corrosion-resistant joining device in which the coating is effected of at least a part (15) of a surface of an element of a joint (11, 12) facing a structural element (20) made of at least one composite material with at least a film of prepreg E-Glass and epoxy resin (13, 113).

    摘要： An ejection device (1) suitable for ejecting a screw (3) after being threaded by a threading machine (2), com- prising: Supporting means (7) suitable for being assembled on said threading machine (2); ejecting means (13) supported by said supporting means (7) and suitable for coming into contact with said screw (3); return means (24) cooperating with said ejecting means (13); said ejecting means (13) being movable between a with¬ drawn position (R) with respect to said supporting means (7), towards which said ejecting means (13) are pushed by said screw (3) due to the movement impressed by said threading machine (2) so as to oppose and mechanically load said return means (24), and an extended position (P) at least partially with respect to said supporting means (7), towards which said ejecting means (13) are propelled by said return means (24) so as to expel said screw (3) from said threading machine (2).

    摘要： The present invention relates to a mechanical torque transmission element (1) such as a nut having a thread (4) on the inner surface (3) of the central hole (2). The thread (4) is obtained by rolling. Nevertheless, no double crests are present because, during rolling, two elevated portions (61) of the crest portion (6), separated by a centerline (62) of the crest portion (6), are deformed so as to be elevated with respect to the centerline (62) and to close up to mutual contact above the centerline (62). A channel (65) inside the crest portion (6) may remain at the centerline (62). Mechanical machining of the end turns (5a, 5b) to obviate the weaknesses caused by their reduced thickness, and a thermal treatment in an oxide-free environment are also provided.
