Abstract (en)
[origin: WO2012136922A1] The assembly screw (1) has a threaded segment (1b), the nominal diameter (D1) of which is greater than the diameter (D3) of its shank. The device comprises an anti-creep ring (4) intended to hold the screw (1) and one of the ends of which has arrangements (4a-4b-4c-4d) able to delimit, before the ring (4) is inserted into a housing (2a) in the element (2) before being screwed, a circular zone having a diameter (D) greater than the nominal diameter (D1) of the threaded segment (1b) and, after insertion of said ring (4) into said housing (2a), a circular zone (D) having a diameter (D2) less than that of the nominal diameter (D1) of the threaded segment (1b) but greater than that (D3) of the shank (1a) so as to act as an abutment for said segment and to enclose the screw (1) in the ring (4) while allowing it limited movement.
