Trying to dismantle a bedframe, but we can't figure out these fasteners. They don't have a washer or anything similar on the other side, the heads are smooth circles so a wrench isn't grabbing them, the heads don't have a slot in the top for a screwdriver or alan wrench to fit into, and knocking at them with a hammer didn't dislodge them.

The bedframe doesn't have any markings on it other than Made In China, so I haven't been able to track down specs, and the fasteners only say 69 on top of the head (presumably just a part number). The shaft of the fastener doesn't have any threading, and the whole thing is only around an inch long including the head
