Question on grounding metal outlet boxes

Hello,

Here is my situation. I have romex wiring (w/ ground) coming off the breaker box to a single metal outlet. Wiring leaves the single outlet and connects over to three other outlets in a chain. My question is how do I properly ground the boxes/outlets?

Here is what I think but wanted an opinion.

1) Take both grounds (one coming in from the breaker box and one that connects over to the next outlet in the chain) and install a "greenie" wing nut which will combine the two into one ground wire.
2) Wrap that single ground wire coming out of the "greenie" around the green screw connected to the metal box and then attach the end of the same ground wire around the green screw on the outlet.
3) Continue this same method down the line for all 4 of the outlets.

Will this properly ground the metal box and outlets?

Thanks!

Yes, that would be an acceptable method.

Your method is fine. But here is another:

Take one of the grounds coming into the box and and connect it to the ground screw. Then join the two ground wires to the the greenie and connect the tail to the device.
