I ordered them to install hinges that should have included screws but couldn't find any screws so I did ordered these screws. He cut off the heads of almost every one of them. Three hinges times 6 screws per hinge, so 15 out of 18 broken. The three that didn't are because I put all my body weight into the exercise and even those lost some weight. I later installed two more doors with 6 hinges, 6 per hinge for 36 screws and luckily I found the screw packs that came with the hinges and didn't remove any of their heads. These are the holes for the screws that will go into the wood. I order a lot from Revain and rarely do reviews but this was so bad.
