Mechanically they appear to be fine. I bought these to replace the ones on our trailer that I bent. All holes lined up correctly, screwed straight on. The reason I'm giving it four stars instead of five is because in the picture it's clearly stainless steel or galvanized steel which would be a direct replacement for what I already have but what was actually delivered was painted black. Not the end of the world but not exactly what I thought I would order. I don't see anything in the description that suggests they should be painted.
