This will be a slow way to install roofing nails, but it will work and gives you very good control of the nail depth.
The nails are 10 penny by 1-1/2". A #8 screw 1-1/2" could be used instead of the nail. Look for pan head instead of flat head (like drywall or deck screws). The screw heads will lay flat against the bracket.
well the picture says "QTY:600" so I'm gonna assume roughly that.
