Query: Don't use the screws supplied

I was not impressed with quality of the metal stamping. 2 of 10 brackets did not have "Press" stamped on them. All the brackets have a twist. Neither of these issues affect functionality. However, don't use the #6 5/8" screws provided if you are installing using a power driver. First, these are flat head screws and should have been pan head. The metal is so soft that the screw head snapped off about 40% of the time. I replaced them with standard pan head screws and had no installation problems afterward.
