Device (10, 20, 30) and method for tightening a bolt (2) or a nut (12) threaded on its end, which end extends through at least a first body (3) and screws into a hole (5) in a second body (4) or extends through the second body into another nut (13). The device has gripping means (7, 17) co-acting with the bolt-head or the nuts. Means (8) process a signal generated by sensor means (18) subject to the axial force exerted on the surface of the first body by the bolt-head or the first nut, or on the surface of the second body by the second nut, and control the device such that the bolt-head or a nut is tightened subject to the axial force exerted on the surface- of one of the bodies, which sensor means are in an annular body (16) around the threaded hole between the bolt-head or first nut and the first body or between the second nut and second body.
Dispositif (10, 20, 30) et procédé de serrage d'un boulon (2) ou écrou (12) à l'extrémité filetée, qui s'étend à travers au moins un premier corps (3) et se visse dans un orifice (5) d'un second corps (4), ou s'étend à travers le second corps dans un autre écrou (13). Le dispositif comprend des moyens de fixation (7, 17) qui agissent de manière concourante avec la tête de boulon ou les écrous. Des moyens (8) traitent un signal généré par des moyens de capteur (18) soumis à la force axiale exercée sur la surface du premier corps par la tête de boulon ou le premier écrou, ou sur la surface du second corps par le second écrou, et commandent le dispositif de telle sorte que la tête de boulon ou un écrou soit serré sous l'effet de la force axiale exercée sur la surface d'un des corps, ces moyens de capteur sont dans un corps annulaire (16) autour de l'orifice fileté entre la tête de boulon ou le premier écrou et le premier corps ou entre le second écrou et le second corps.
