For fastening the nest box to the sides of the pen, I use these items: ring clip pliers, an eye bolt, a nut, 2 washers, a cage ring (small “hog” ring), and a swivel snap hook.
I fasten together the eye bolt and the snap hook using a cage ring.
Here they are after they are fastened together,
I make two small holes (the size of the eye bolt), in the sides of the tote. Then I screw the eye bolts in.

The swivel hooks are on the outside of the tote.

I use the swivel hooks to fasten the tote to the wire sides of the pen. The bottom of the tote is on the ground. I have to fasten the totes so they don’t tip over when the chickens land on top of them.

My evaluation of using plastic totes as nest boxes:
Easy to clean
Available in a variety of sizes
Easy to access the eggs by lifting the lid
Will eventually succumb to weather/sun damage if used outdoors
Tip over easily if not anchored in some way
