When I was doing commercial/residential electrical work back in the 70s, we
used copper Buchanan splice crimp connectors for the bare ground leads in
the steel boxes.

With the ground leads exending out of the box, they were twisted together
firmly (just outside the box), then the crimp connector was slid down over
the leads to the center of the twists, and crimped.
That leaves 2 long pigails that can be trimmed to an appropriate length, to
secure to both a box screw and the receptacle strap earth ground screw.

While the capacity for the crimp connectors is up to 4- #12, slipping them
over 3- #12s that are twisted is all that will fit in them.
If more earth ground leads are needed, a long 3rd lead could be added to the
twist (about 12" long, twisted at about the middle), leaving 2 more securely
bonded pigtails.

I imagine some inspectors will be suspicious of anything that's not a more
recently approved product, such as the greenie nuts with a hole in the top,
but the Buchanan splice connectors have been used without problems for
decades in building wiring, inside appliances and other elecrical
equipment.

I've read comments of some inspectors that fail wire nuts used on ground
leads if they aren't green.

The thing I get irritated with is the single ground screw, which means
you keep having to fark around with a pigtail and wirenut to run a
series of outlets. Most of the time THREE places to connect a ground
wire would be really nice (in, out, box.) Two would work well enough
(just leave one wire end long to connect to the box) but one is
frustrating.
