A double-hinged gate hinge including a pair of pivotable members, such as a pair of links of chain, one end of each pivotable member being secured pivotally to a hinge pin receiving block and the other end of each pivotable member being secured pivotally to a fitting having a bore extending therethrough. Upon the hinge pin receiving block being placed on one side of a post and upon a bolt, such as a U-bolt, being placed on the opposite side of the post, and upon the threaded ends of the bolt being passed through the fitting bores and upon threaded nuts being secured to the ends of the threaded bolt, the hinge pin receiving block and bolt being drawn towards each other and the pivotable members being caused to pivot with respect to the hinge pin receiving block and experience double-hinge action and thereby conform generally to the post and posts of different diameters. In one embodiment, each pivotable member is only pivotally mounted at one end, the end connected to the hinge pin receiving block, and the other end of each pivotable member is provided with a radially outwardly extending portion provided with an oversized bore for receiving the threaded ends of the bolt whereby the gate hinge may be secured to posts of different diameter.
