ABSTRACT:
A pair of laterally spaced apart, registered and parallel plates are provided including two pairs of corresponding opposite side marginal edges. A pair of elongated parallel spacer members each extend along and are secured between a corresponding pair of side marginal edges of the plates to define an open ended sleeve of rectangular cross section wherein the spacing between the spacer members defines a major transverse inside dimension and the spacing between the plates defines a minor transverse inside dimension of the sleeve. The sleeve is open at its opposite ends and one end portion of a drive shank having a diameter substantially equal to the minor dimension of the housing is secured in one end thereof between the plates and against and paralleling the inner surface of one of the spacer members. The other end portion of the drive shank projects endwise outwardly from the sleeve and includes a free end including structure for releasably coupling a rotary torque tool thereto. The end of the shank secured within the sleeve terminates inwardly of the sleeve a spaced distance outwardly of the longitudinal mid-point of the sleeve. When a J-hook has its hooked end telescoped within the end of the sleeve remote from the drive shank and abutted against the latter the drive shank is automatically aligned with the threaded shank of the J-hook.
