These are decent, heavy-duty swing hangers. They include hardware, but that's actually why I knocked them down one star. The hardware included consists of lag bolts, which I would never recommend for an overhead application. I drilled though my top bar (4x6 PT lumber) and used through bolts with fender washers on the top end. Lag bolts can work loose over time, and the damage may not be obvious until the connection fails.
