Tommy, I can't remember what mine said, might be nickel, certainly wasn't Stainless. That said, the vent doesn't get all that hot really. I doubt it would be a problem. Try another HD store. I got mine on the spot - in those large drawers they sell individual pieces from... nuts, bolts, washers, lock washers, etc.
yea that is where they had the other plugs. They didn't have any stainless or nickel. My vents get pretty hot.
