Abstract: A magnetic lifter device having a housing with a work piece engagement face. A support structure comprises two clevis-shaped members having, respectively, legs whose terminal ends are hinged to opposite, exterior side faces of the housing at respective fulcrums located close to the engagement face and the clevis-shaped members straddle the housing across a width thereof. The relative positions of the fulcrums and the length of the legs are selected such that at least one of the clevis-shaped members may be rotated away from a first operational position of the lifter device, in which both clevis-shaped members converge to form a common hoop for insertion of a coupling member, into a second operational position, in which the work piece engagement face has been rotated by about 90 degrees from its orientation in the first operational position and its head portion remains clear of the housing during said rotation.
