A couple of pot metal mystery items.

They're not found together or anywhere near each other. The first item was found in a campground and appears to me to be fire fighting related. They're the only ones I know of that use 5 sided bolts, but, ?? The bolt is non-magnetic stainless steel and the housing it's in is some sort of aluminum/magnesium/pot metal alloy. It's not broken off that I can tell. There are numbers on the octagon shaped end "P 35?" and "304 C" is on the head of the bolt. Something ferrous was probably under the head of the bolt at one time. The rusty remnants are still clinging there. The second item was found in a field with LOTS of history, although, I don't think this is particularly old. There again, it's made of some sort of aluminum or pot metal. Looks like it was cast in a 2 piece mould as there are seams on the sides that line up with the centerline of the hole. The hole is not threaded (or ever was that I can tell. The whole thing is slightly tapered and looks like it was a wedge fit into something at one time.

I've seen these before and I think the first 3 pics show a leveler that I think had something to do with Iron porch railing. The lumber store kind. I don't remember the five sided bolt, but the 304C is the designation for the stainless alloy it's made of. 304C is just barely considered stainless because it still contains a significant amount of iron and is generally attracted to a magnet. It's usually used indoors or in a application that's covered outside. The lower photo on the left looks like a concrete anchor. Not sure about the right.

looks like an adjustable appliance leg

A leveling device is certainly possible, but, I would think it would have a round headed bolt instead of a 5 sided one. How would you get a wrench on it to turn it once it was in place? I guess you'd have to turn the housing?

I have adjusted some stoves that had levelers like that with same type of bolt heads and the other item looks like a cable lock seal.
