Not sure but wild guess would be cutting a key hole shape - ie drill a hole and extend a slot from it.
Screw head fits through the hole then slides into the slot to secure it. As in the bracket below.
Would think they'd only suggest this where you cant get to the rear of the panel your attaching the bracket to.
May be wrong though!
