Abstract
A hinge pin construction including a pin adapted to journal an arm or the like, an annular wedge member associated with one end of the pin, a collet receivable on the wedge member, a bolt extending through the collet to be threadably received in a bore in a pin, the bolt also being threadably received in the collet. The threads in the collet have a lesser pitch than the threads in the bore so as to provide a differential action to properly seat the collet on the wedge member with a minimum of friction.
