ABSTRACT:
An apparatus including a plurality of jack bolts which 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 a shaft by a retainer, a nut on a threaded end of a bolt, or the head portion of a bolt. The jack bolts can be arranged in a flange on an end of a tension rod to stress arbors against opposite sides of a roll sleeve to form a roll assembly for use in a rolling mill. The apparatus includes structure for preventing escape of the jack bolts from the flange which is particularly advantageous when the apparatus is secured to moving machinery where the presence of escaped jack bolts could cause damage to the machinery.
