Drill a 20mm hole through the post section at each hinge height. Pass each bolt through, fit the washer plate and nut on the far face and nip them up. Stand the gate on packers in the opening, hold each back plate flat on the side of the stile, then mark, drill and fix it through both holes with M10 bolts, or M10 coach screws in timber. Take the packers out, wind the bolts in or out until the gate hangs square and swings clear, and tighten the nuts hard.\u003c\/p\u003e\n\u003cp\u003eThe bolt has 42mm of thread and the nut and washer plate take up about half of it, so this hinge suits post sections up to about 20mm thick, such as flat bar or angle, where you can reach the far face.
