A reaction nut for location on a threaded bolt, particularly a bolt to be tensioned by a hydraulic tensioning device, comprises a plurality of internally-threaded segments (22) movable between an outermost inoperative position radially spaced from the bolt (2), and an operative position making threaded engagement with the bolt (2), the segments (22) having tapering surfaces thereon, a primary ring member (16) movable axially relative to the segments (22) and having a corresponding tapering surface (18) thereon, first resilient means (20) biasing the tapering surface (18) of the primary ring member (16) into engagement with the tapering surfaces on said segments (22), and cam means (26) actuation of which moves the primary ring member (16) from a rest position to an axially displaced position against the bias of the first resilient means (20) whereby the segments (22) are moved by associated second resilient means (24) between their operative and inoperative positions.

Un écrou de réaction devant se placer sur un boulon fileté, notamment un boulon placé sous tension par un dispositif tendeur hydraulique, comprend plusieurs segments à filetage interne (22) pouvant être déplacés entre une position inactive extérieure éloignée du boulon (2) dans le sens radial, et une position active permettant au filetage d'entrer en prise avec le boulon (2). Ces segments (22) présentant des surfaces inclinées, une bague primaire (16) pouvant se déplacer dans l'axe par rapport aux segments (22) et présentant une surface inclinée (18) correspondante, un premier dispositif faisant ressort (20) et plaquant la surface inclinée (18) de la vague primaire (16) en prise avec les surfaces inclinées des segments (22), et une came (26) dont l'action fait passer la bague primaire (26) d'une position inactive à une position déplacée dans le sens axial à l'encontre de la force exercée par le premier dispositif faisant ressort (20), ce qui permet de déplacer les segments (22), grâce à un deuxième dispositif associé faisant ressort (24), entre leurs positions active et inactives.
