Specialty bolt - Lag bolt with attached coupling nut?
"5thumbs"--Personally I would not recommend this type of hanger for shelves. You are depending on the strenght of the lag bolt within the wood to support ALL of the weight on each hanger you install. I've seen too many of these fail. IF you found what I think you found, it has "lag bolt' threads on one end, and female machine threads on the other, and probably has slits in both sides which are used to screw it into the wood with. (Brain fart here) But for the life of me I cannot remember the name of that bolt. I believe you would be better off using a type of hanger that attaches to the sides of the rafters, using screws to anchor in place, and will accomidate the threaded rod with washers and nuts. Good Luck, David Another thought here: IF I were looking for the aforementioned bolt, I would try a web search at McMaster-Carr. I use them a lot.
