Stainless is best for things like shackles, nuts, washers and lockwashers.
Hot dipped galvanized hardware lasts a very long time. Electroplated
hardware (zinc) must be painted to avoid rust. Avoid stainless steel
bolt/nut combinations that will need to be torqued tight. There is a
tendency for the threads to gall, and once galled, the nuts are virtually
impossible to remove. A good example to avoid is all-stainless u-bolts.

either Home Depot or Lowes in Fredericksburg, VA or Alexandria, VA.
So, maybe it varies with Home Depot and Lowes, and maybe not. Look for the
three tick marks on the bolt head. Whatever I bought was galvanized, and
not stainless. I find the latter undesirable for the price, because it is
too easy to paint galvanized hardware for long term protection and it is
