I used something similar but for timber: demon nuts. Very useful if you need to be able to screw a bolt in and out multiple times or for better strength than timber alone.

I really like the idea of the fold-down table but decided against it. The fridge slide would collide with it.
Instead I went for a push-to-open table at the bottom of my storage system. I can have it and the fridge slide out at the same time. Very handy to get things in and out.
