Abstract
A demountable pin for rotatably connecting together two elements of small axial dimension, consisting of a bolt with a frusto-conical under-head and an inner hexagonal through bore for tightening it by a key. The pin is locked between two frusto-conical flares of the elements by an end nut with a frusto-conical under-head and a washer with a frusto-conical surface of greater taper than the flares. The under-heads of the nut and the bolt cooperate with the flares.
