AKA "book screw"NJMike:From the Diveriteexpress website, on the nylon mesh sleeve:
We suggest using your choice of either TWO plastic or S/S sex bolts to easily attach the sleeve to the side or bottom of a backplate.
What is a sex bolt?
SS links work as well or maybe better. Sleeve is more flexible.
I have used zip ties too although if you twist em they will break.
