I picked up some of these today at the last flea market of the season. Heavy lag-type spike with a single bevel nose. The head is pressed on. The head is forged not stamped. It is not threaded, but has two ridges running its length, and raised ribs that look a little like threads. What are they called? What are their use(s)? Thanks!

That looks like #4 rebar with 1/2" or 5/8" nut twisted on top and then painted with galvanzing spray.
Maybe a garden tie spike? Them 3x5 PT ones? You are right about the parts for sure.Spheramid Enterprises Architectural Woodworks

It is the original Simpson anchor bolt. Some left a chunk of bar sticking out of the crete and Mr. Simpson turned a nut on it. Retails today for $5/unit.
Yahoo! I can retire! I only paid 25¢ apiece for them.
I can't see threads on the inside of the head. The head may be welded on, but only at the top.
You are right about it looking like rebar.
"The head may be welded on, but only at the top. "
That would make sense, since the head is at the top.

Sure, you can trust the government - Just ask an Indian.
The following is a guess only - have never seen same.
Removable 6" spike -- hammer driven into place, back out with wrench.
You know the gray plastic covers which you see on the sides of utility poles? Look kind of like 1/2 of a piece of PVC conduit with nailing flanges? I used to work for the company who invented that stuff - we marketed it as "PowerMold", company I worked for marketed it poorly; product was sold off to another company who really got it into the utility market. A cheaper / faster replacement for conduit up the side of poles.
The recommended installation method was to drive in 1/4" x 2" or 2-1/2" lags through nailing slots in the flanges. If you needed to remove the PowerMold at a later date - you could back the lags out with a wrench with no damage to the PowerMold.
Perhaps the hardware shown would work in a similar fashion, but drive easier?
Kind of an overgrown duplex nail / screw hybrid?
Pure guess.

Never underestimate the value of a sharp pencil or good light.
It does look like it needs to be driven into a pre-drilled hole. The heads don't look like they would take a good whallopping without coming off, a moderate beating yes, but not a really heavy set of blows. Thanks for the reply.
This looks like a 'thunderbolt' masonry anchor, which is screwed into a pre drilled hole.
They are similar to thunderbolts, but different. These look like they should be driven in (hammered) instead of screwed in. They have two opposing ridges that run the length of the shaft. These ridges are the same height as the raised threads and would ream out the hole if turned, disallowing a purchase by the threads.
I really must quit buying stuff at the fleamarket that I am unsure of, but I can't - wife says it's a sickness!
