These hinges are fantastic. They're very heavy duty and worth the money. And don't mind my welding skills, it works for my hobbies.

wait, what?
I've previously bought other hinges of this same style and at the same price, and their manufacturing bordered on rubbish. These MHM hinges are beautifully machined. However, there's one completely baffling flaw: the pins have no heads on them. They're free to slide all the way through the hinges, which they do quite easily.The ad does indeed show both ends of the pin just as I received them, so that's an intentional feature. I missed it. Is the idea really to hope that side tension on the hinge overrides gravity (it doesn't; the pins simply fall right out with ~30 lbs hung from the hinges), or are you supposed to weld a head on them yourself? Or drill and pin one end? Or are they only meant to be used horizontally??Great product aside from that one fatal flaw. Totally unusable as-is, thus a 1-star rating. I'll either replace the pins with bolts or weld washers on top. I've never seen door or gate hinges with headless pins, and can't imagine what the thinking was behind this design.
