Abstract (en)

[origin: GB2402188A] A hydraulic fastener assembly includes a stud (1) that includes a screw threaded end portion, a screw member (5) around the stud and a sliding member (6) on an axially inner side of the screw member (5) slidably mounted on the stud (1). The arrangement is such that when in use the hydraulic fluid is passed into the assembly the sliding member (6) is pressed axially inwardly and hydraulic pressure forces on the screw member (5) are substantially balanced axially thereby facilitating screwing of the screw member (5) axially along the stud (1) towards the sliding member (6).
