connecting multiple grounds in junction box

I need to connect 3 separate grounds in a junction box.
The box has 4 screws at the back.
Can I just connect reach ground to a separate screw or should all grounds be directly connected to each other?
As it's a metal junction box I presume it doesn't matter as any screw will ground to the other.

You should connect one wire to an installed green ground screw in the back of the box and then twist all the grounds together and cover with a marette.
