I'm making a corner shelf for spare toilet paper rolls from 6.5 mm laminated plywood.
I'm going to order CNC cutting of the shelf.
I want to go some fancier way than just screwing l-brackets to the wall and the shelf, for the sake of experience.
On this picture -- the wall would be vertical, and I'd have anchors installed in it. The bolts would replace the nuts, and I'll need extra groove for a hexagon to rotate the nuts into wall anchors.
The question is: Is there some specific bolt head type best suited for this kind of job?
