My boss was always kinda tight about buying certain items, one being 4 squares with brackets or Caddy H23 mounting brackets for use on steel stud jobs. We were told to use 1/2"X#8 tek screws thru the two tiny holes near the front on the side.
This was no picnic, as the holes were too small and you were really in need of three hands to do it quickly. Lots of bad language floated around during several consecutive all day "boxing sessions" on large jobs.
Along came a new inspector. He said those holes were not allowed to be used for mounting. We could not prove otherwise (what else would they be for?) but we workers then had all the authority we needed to tell the boss "Stop carrying 88 cents a box on your takeoffs and get us Caddy H23 brackets or side bracketed 4 sqs."
I loved that inspector, right or wrong, and the quality of the job was improved. All future jobs were much easier as well.
What had actually caused the inspector to question it was the way those of us who wanted a tighter mount screwed one tek screw back thru the stud into the side of the box creating a pointed "hazard" inside the box. You do what you have to to be satisfied with your mechanical soundness.
