Abstract
A low-friction hub assembly for pivotally connecting a pair of scissors employs a pair of cooperative hub nuts. A first hub nut has an exterior threaded surface which threadably engages with an interior threaded surface of the second hub nut. Each of the hub nuts has annular shoulders which engage against opposed annular surfaces of surrounding aligned pivot openings of the scissors. A pair or opposed pawls engages a serrated surface to lock the subassembly. A throughbore extends through the pivot assembly.
