ABSTRACT OF THE DISCLOSURE The invention provides a chain grab hook for suspending a load, which comprises a hook body including a shank having an eye by means of which the hook- is suspended in vertical attitude, a bight integrally joined with said shank and a free end portion integrally joined with. said bight. The shank, bight and free end portion lie in a common plane generally forming a C-shape to define a throat. The free end portion has a substantially flat upwardly facing support surface defining the lower side of the throat and the free end portion has a generally vertically extending depression in its opposite sides whereby the support surface in plan view presents a widthwise elongate support surface portion at the innermost end of the throat and a narrowed portion of reduced width. The elongate surface portion supports the barrel portion of a chain link received in the throat and the width of the narrowed portion is such as to receive bight portions of adjacent chain links. The shank overlies the support surface to define the upper side of the throat and has down- wardly and laterally outwardly facing abutment surfaces on opposite sides thereof to engage the bight of one of the adjacent links to thereby force such bight also against an edge of the narrowed portion when the other of the adjacent links has a load suspended therefrom. The depressions are laterally offset from the eye whereby the hook is both rotated in its vertical plane and tilted to one side relative there to when the chain supports a load.
