ABSTRACT:
A radially expanding bolt assembly has a hollow element insertable into a hole of an object and having an inner surface with at least one inner surface portion which is tapered, an expanding element insertable in the hollow element and having an outer surface with at least one outer surface portion which is tapered and cooperates with the inner tapered surface portion of the hollow element, additional elements for displacing the expanding element in opposite axial directions for tightening and loosening the bolt assembly, and a washer positionable between the object and one of the additional elements at one of the axial ends, so that the one additional element displaces the expanding element in one axial direction and due to cooperation of the tapered surface portions expands the hollow element to clamp it in the hole of the object, while the other additional element displaces the expanding element in an opposite axial direction and the tapered surface portions disengage from one another so that the hollow element contracts and the radially expanding bolt assembly can be removed from the hole of the object.
