A method of clamping and locking a roll for a steel mill on a driving pinion comprising applying a side thrust force against a roller to clamp it against a shoulder on the pinion whilst applying the reaction force produced by the side thrust force to cause a plug located in a cavity in the pinion beneath the roll to move sideways. The plug is provided with threads which when the plug is moved sideways produces a wedging action which expands the mounting surface on which the roll is mounted to lock the roll on the driving pinion.
