I have a large-ish screw hook in some drywall that is only supporting a dustpan and hand brush. The hook is not in a stud. As-is, the weight is not too much and the solution works. However, I am always afraid of ripping out the hook when I remove or replace the dustpan, and I can see that the hook is rather wobbly in the wall.
I would like to somehow make this more secure. The issue is that I cannot find any anchors large enough to fit the screw hook. Is there some alternate way of making this hook more secure? This is a garage, so I am open to solutions that might be considered unacceptable for interior use.
