ABSTRACT:
A hookbolt adapter for use with a bolt in order to convert the latter into a hookbolt, the adapter comprising a hole through which the shank of the bolt can be taken, a nose portion and a tail portion diametrically opposed to each other with respect to the hole, and a support surface to be engaged by the head or by the nut of the bolt. The hole is of circular cross-section and the axis of the hole is slightly inclined to a line perpendicular to the support surface, and two diametrically opposed substantially semicircular contact portions of the wall of the hole serve to retain the bolt rigid with the adapter when the axis of the bolt adopts a position substantially perpendicular to the support surface.
