Well they work. The blows on them must have been blunt as they weren't really flat. and the included screws are fine as long as they are not flush installed. (They stick out decently at 1/16". Luckily I have a few that are flush mounted and a hammer and anvil aligned the brackets well enough to work for me. On the other hand these are good solid L- brackets. .
