Just simple light fixture ground wire question

I need to replace an indoor light fixture (typical 60 watt max metal dish shaped with glass globe). I know I need to connect white wire to white wire and black wire to black wire. Light fixture has copper wire (no green wire)

I notice the ceiling receptacle has a copper wire grounding screw. Now I hear different answers on this. Some people just connect house copper ground wire to fixture copper ground with wire nut and omit the grounding screw. Others say they first wrap copper ground around receptacle screw then wire nut both copper wires together. And some say you can do it either way.

Should I wrap both copper ground wires around screw and then wire nut both copper wires together. Or just wire nut connect both wires?

Correct.

The incoming ground wire should be connected to the box first.
Then the end can be connected to the fixture with a wirenut.

By 'incoming' you mean the ground wire coming from house? Can you also wrap both copper wires around grounding screw first? What if you just connected both copper wires without first connecting it to ground screw on box?

The PROPER method is that the ground wire that is coming in with the power cable gets connected to the box first with a green screw at the back of the box.. After that you can do what you want.

Understood Pete. I've seen that green screw before. The only screw on this particular box is silver not green

Only one wire under the screw head.

The light fixture kit came with a bracket with a green grounding screw. The bracket can be screwed to the existing box. Thanks

The fixture bar comes with a green ground screw for when the box does not have an available ground wire but is grounded..... like with BX cable.

The ground wire from the fixture would attach to that green screw on the bar. In your case.... you have a ground wire in the box. That green screw in the fixture bar is not needed.

I already finished the wiring according to what was said below. But sorry, I don't understand your last answer Pete.
