Abstract
A stud for interconnecting adjacent flanges of a flanged joint in a tubular casing. The flanges each contain apertures to receive the stud and each flange is inclined relative to the casing outer surface, with one flange extending radially outwardly and the other flange extending radially inwardly, as a result of which one end of the stud extends externally of the flanged joint and the other end extends internally. The stud includes an external formation that is of non-circular form and that is carried by the stud between the threaded ends to extend radially outwardly. The external formation is adapted to be engaged by an anti-rotation member to prevent unintended rotation of the stud. The stud is removable from the flanged joint without the need to completely disassemble the joint to remove a broken stud.
