Abstract: An expansion bolt including a housing member integrally formed as a single piece of material, the housing member having a base, a plurality of elongate elastic members extending distally from the base, the elongate elastic members distally terminating in respective spoons, and the elongate elastic members having thicknesses that are substantially less than thicknesses of the base and the spoons, a central shaft member extending through the housing member and terminating in a wedge member, the spoons defining a cavity for receiving the wedge member, the elongate elastic members structured to bend outwardly in response to the wedge member moving into the cavity, and a biasing member for biasing the shaft member relative to the housing member in the direction of said increasing relative translation.
