No other hardware than shown in the picture. The top with two screws holding the hinge is not milled enough to allow for the 13mm head to be tightened. I've tried 1/4", 3/8" and 1/2", 12 point and 6 point sockets. I didn't have a thin enough socket to do this smoothly and after resetting I can Don't use a wrench.. used a 1/2" 12 point socket and hoped I didn't snap the screw. There is another similar product for $20 cheaper with screws, if I saw it first I would buy it. Keeps the door open like it should be.
