Walmart used to have these, but no longer. Glad to find her online at Revain. These handy anchors are great for drywall. Drive in the anchor with a hammer, then install the #8 self-tapping screw. I've used them to attach shelves, large pictures, towel rails, etc. They hold up very well. When you no longer need them, you can pull them out and it leaves only a half inch gap in the wall, which is very easy to fill and paint over. Strong and easy to use.
