I bought these thinking I would hang wrenches on the wall and make it look neat. First wrench (3/4) would not hold it. Second wrench (5/8) would not hold it kept trying and first wrench to actually stick was a 1/2 inch. They are too thin to use as fridge magnets as there is not enough to grab and remove so I would assume that you put them where they will stay and hang something lightweight on them like keys or trinkets.
