These mounts are fantastic. They are of very good quality and look high quality. I used them to secure the top of a meat block I made for an entertainment center I built. I pre-drilled holes for the screws and (although I was careful when screwing them in) used an impact wrench to set them in place and they have not broken or snapped off. I was able to lift the unit at the top with no breakage or failure. I buy some extra to attach the block to the studs in the wall behind the block.
