These were recommended to me rather than normal galvanized 1/4" size lag bolts. We'd like to hang our porch swing from the 2x8 joists of the pressure treated deck. What is the load rating that these can support for a vertical hanging structure? Note that the brackets I have are two screws/lags per bracket. (Two brackets=4 total screws/lag bolts)
Asked by: Anonymous
These are much better than 1/4 inch lags. I am going to use them all over the farm now
