Abstract
A coupling between adjacent ends of transfer bar sections which includes a screw having threads of opposite hand at opposite ends thereof engaged with threaded counterbores in the ends of the two transfer bar sections. A spacer ground precisely to a desired length is clamped between the ends of the bar sections when the screw is tightened. The spacer and screw have radially aligned holes therein to accommodate a tool for tightening the screw. The holes are dimensioned relative to the tool so that the screw can be tightened a final increment without rotating the spacer.
