Service panel bonding

Does anyone see how this service panel is bonded to ground?

The green screw just beneath the service disconnect. . .

It didn’t look green to me, I’m partially color blind.
Thanks Jeffrey.

Don’t look for green screws, unless they stand out ofcouse. Look at the wiring diagram on the side of the panel. It usually has a drawing showing where the box bonding screw is located (if needed).



Thanks Tom.
