The metal junction boxes that we are installing receptacles in have no ground screw just holes in the back for mounting and knockouts How do you properly ground j boxes?
DaveM357
Make your own ground screw. Use a #8 x 1/2"or #10 x 1/2" sheet metal pan head screw and screw it into one of the holes in the back of the box. In the back of the box you might see a raised portion where the original ground screw came out of, use that hole. Wrap the ground wire around the pan head screw and it will tighten up very nicely and make a good ground.

How do you install a mounting plate for a ceiling light?
The mounting plate for a ceiling light is designed to be mounted to a round or octagonal ceiling box. Very often these can be installed in existing structures without too much trouble. Without the box it is a code violation. Splices must be in enclosures and hanging loose in the ceiling doesn't qualify. If you do not have a box in the ceiling, you might consider installing a box ON the ceiling. It would be only 1 to 1 1/2 inches deep. Your splices would be safely inside. These boxes are typically used in outside installations and come in white or gray and take paint nicely so no one may ever notice. This type of installation is acceptable if the box is properly mounted.
