Grounding an outlet to a box

Hello,

In my house the ground wires were never connected to the outlets. It seems the grounds were cut so there were only two inches long and connected to the metal box with a screw. Due to their short length it is difficult to connect the outlet to them. Is it acceptable to put a ground wire around a second screw on the grounded box to connect to the outlet ground? Thank you.

So long as it is a tapped hole and you use an 10-32 machine screw that is fine or you could use self threading machine screw in a drilled hole or you could use a self grounding receptacle. It is better practice to use green ground screws made for the purpose. You can't use a sheet metal screw.

I used the screw that pushes the clip on the switchbox to hold the wires down. There are no wires on the clip. Is this acceptable?

No. It should be in under a screw intended for only a ground wire. Unless it is a very old box there should already be holes in the back of the box for that purpose.

Just an FYI: ground screws/holes are 10-32.

No, but removing that clip and its screw to increase space in the box is not only acceptable, it is standard practice. And since the screw you removed is a 10-32 machine screw, you now have a tapped hole to run your ground screw into.
