These works. My husband and I are not tame people. We tried to attach the hose holder to a wall with concrete screws. They wouldn't hold back. I ordered these, put them in, cut off the excess and put in new screws. They held the screws very well. Now we are DIY warriors. I may also add, I ordered 2 packs but only received one. I contacted the seller and he responded almost immediately with an offer to return the money or replace it. Excellent product and service.
