I ordered these to be the hinges for the top of a keepsake box I was making for my grandson. They were perfect for the application. I only had one problem that was my fault, not the hinges. The hinges come with 1/2" nails, but I had to drive them through a 1/4' lip. I simply used my dremmel tool to file down the points that came through the lip. Problem solved.
This is a nice hinge, but made of a very light material. I did not like that the fasteners were small brads, not small screws. For my project, this was not a good solution. For lighter material projects, these would probably work well.
