Anyone have these? What is the rail like that they sit on- can it be screwed to the wall and how liable are they to fall off it? I have had a couple of sets in the past with plastic trays etc and they are constantly falling out or getting lost
12 point bolts are not uncommon. https://www.aftfasteners.com/12-point-flange-bolts/ Enjoy removing those with a six point socket
i would never buy a 12 point set ever they round nuts.
