I actually bought these to hang up small tools and other things in my garage. I wanted something sturdy so they could hold a bit of weight and these are perfect. They are a decent price as well.

I haven't broken one. I prefer this flat head style to the ones that the head protrudes. They're a great value for the price. Time will tell how well to coating holds up.
