If you happen to have information about these bolts--how old they are, how they work (i.e. what type of bolt they are), what size they are,etc.--please post information here.
I would be grateful.

Pictured is one of the most common forms of bolts found at Stoney, shown along side a modern bolt hanger for comparison. They can be found atop many different formations.
