Hangers I'd say less than 2.00 (10mm) from what i've seen so far. Not sure about bolts (3/8 hole) still checking around. I think they better be SS considering the environment they will be in.

looks like we've been using plated steel all along, for some reason I thought we'd used SS, thank God for that, SS is freaking expensive. I think $1.65 hangers (10mm plated steel) is the cheapest so far. Anyone seen better than that?
