I’m extremely disappointed with these. The parts themselves seem to be good enough quality, but whoever did the measurements on the hardware must have been high. The F nuts don’t fit past the tip of the screws, so it’s impossible to secure the 8 pieces that need that screw. Similarly, the C screw holes are not deep enough for the screws. Trying to push them further manually is stripping my tools. The C screws are what connect the tray to the legs, so this set is completely unusable. Very disappointing.
