ABSTRACT:
A fastener and tightening device for exerting force and equalization of force upon the nut or head of a bolt or threaded stud. The device is comprised of a shank fitting through a support member within an abutment head adapted to be drawn up tight against the support member. A plurality of jack bolts are threadedly engageable with holes in the head and are adapted to be tightened to exert pressure against the support member. Separate ball members are positioned between the jack bolts and a wear plate on the support member to minimize friction and provide for force equalization to counteract any off center alignment. The tightening device is particularly useful in a fastening device for equalization of pressure and stress gauging where the shank has a bore receiving a gauge pin fixed at one end in the bore with an opposite end extending through the head to support a rotary gauge which is free to rotate until the shank is stressed sufficiently to tighten the gauge against the head to indicate proper tensioning of the shank. By the use of the jack bolts appropriate tightening can be effected with proper equalization of force.
