I received these hooks today. After I opened the package I can see why there are so many negative comments on the screws breaking or stripping the head. I also noticed like other comments that the backs have a crown on them.Now let me tell how I installed these hassle free without winding up mad with a headache. First you will need a piece of 120 grit sandpaper. Lay it on a flat surface, grit side up. Lay the back of the hook on the sandpaper and start sanding the back of the hook. This goes very quickly since they are made of aluminum. The problem is from the casting process. If they took the time to grind the back flat the end product would probably cost more.Now the screw, yes these are small and delicate. But can be put in with none breaking or stripping. First take a 1/16th drill bit and drill a pilot hole where your screw are going. Then I used a trick my grandfather taught me. Drag the screw across a bar of soap so you have a little of the soap on the screw threads. The soap acts like a lubricant and the screws go in with very little effort. Oh and use a #1 Phillips bit. It fits the screw head properly. Just to let you know my hooks were mounted on a piece of red oak.
