Our local hardware store carries one size of crimp fitting for crimping the ground wires together in a box. Some of the boxes in my kitchen remodel have more ground wires than will fit in a fitting, and, while I can use wire nuts, they take up a lot of room. I ran the line ground wire to the grounding screw in the metal box in all cases. Is it permissible to run the line ground through one crimp fitting with however many wires I can fit in, add a second crimp fitting, and crimp some more wires in the second one?
Incidentally, the issue is not excessive wires for the box - I did that calculation, and I'm OK.
