What are these threaded holes for?

6 of them. Seem to be threaded and factory.
2 near the drain holes, 2 in the opposite corners and 2 on the bulkhead that the gate rests against near the bed rails. Anyone else have these?

Not factory. Someone has added those, dunno why.

Thx. Was hoping there was a factory tie down anchor to go in there. Lol
