A plurality of jack bolts are threadedly engaged with openings in a flange on a fastener to stress a shank part of the fastener. The flange can be a collar retained on the shaft by a retaining device, a nut on a threaded end of the bolt or the head portion of the bolt. The jack bolts can be arranged in a flange on an end of the tension rod to stress arbors against opposite sides of a roll sleeve to form a roll assembly for use in a rolling mill.
