Abstract: An extraction device (10) for facilitating removal of a sheared fastening element (13) in threaded engagement with a member (17). The extraction device (10) comprises of a hollow body (30) defining a cavity (33) for receiving an exposed portion of the sheared fastening element (13). The body (30) has a first face (31) onto which the cavity (33) opens to define an opening (35) through which the exposed portion (29) of the sheared fastening element (13) can be received, The cavity (33) has a boundary wall (35) with an inwardly stepped configuration (45) in the direction towards the opening (35). The stepped configuration (45) presents at least one edge (49) which facilitates welding of the body (30) to the exposed portion (29) of the sheared fastening element (13) received within the cavity.
