Had to hang a 2 hole bracket from the ceiling. 8" I couldn't get the anchor all the way in the hole -drill with 3/ 8" both anchors fit well. The bracket holds a pendant light with a tension chain so I had to be careful when pulling it not to come out of the ceiling. I used the screws that came with the anchors. Now I'm mine pretty sure it must be a lot of weight to get that out of the ceiling.
