I am replacing the circuit to our stove and am doing the rough in currently. We may one day want a stove requiring more amperage than our current 40 amps and so I am replacing with 6-3 w/ground. I have the wire stripped back and pulled into the metal receptacle box and am trying to find a code compliant way to connect the bare ground from the cable to both the outlet and the metal box. I have seen and read about numerous different ways to do this but don't know what is code compliant.
I have looked into purchasing a grounding pigtail and read that any grounding wire I purchase to help connect the metal box to the wiring and outlet needs to be 10 awg as this gauge is good as a grounding wire up to 60 amps. Because the 6-3 is good for 55 amps the 10 ash as a grounding wire is what I need. If I am wrong about this please let me know.
If I can go with a pigtail then…
-
where do I find a 10awg pigtail? I can only seem to find 12 awg pigtails.
-
If i can't find a 10 awg pigtail then is green insulated thhn wire in proper gauge acceptable?
-
how do I connect it all? Can both the pigtail and the bare ground from the wire be placed into the receptacle and screwed down or is there a different way I need to connect them?
Thank you for your input and if I left out any needed info please let me know.

Take the #10 AWG ground from your cable and loop it to your metal box with a 10/32 grounding screw. There should be a threaded hole for this in the box. Extend the ground outward an attach it to your outlet.
