KC Jaguar TOM bridge orientation?

[Bakesalee]

Hello! My low e is slipping out of the saddles so I’m questioning if I put the TOM bridge on upside down. There is a side with hexagons nuts and a side with the screw heads. If the guitar was resting in a stand with the headstock up toward the ceiling, which side does the hexagon nut side of the bridge go? Up or down? Thanks!
