Abstract
A split master link has first and second halves joined along a line of separation defined by toothed and ramp portions arranged such that a gap exists between the tips and roots of the mating teeth when fasteners holding the link halves together are loose. The gap dimension is chosen such that when the fasteners have been tightened to the extent necessary for establishing a desired prestressing of the links through the action of the ramp portions, the tips will have bottomed out. At this time, a significant portion of the desired clamping load will be available through further tightening of the fasteners for forcing the tips and roots together so as to establish a rigid, non-loosening joint.
