Reduce Costs by Using Captive Screws
What is a Captive Screw?
Captive screws are designed to lock into a hole while allowing the fastened components to be detached without the complete removal of the screw. Thus a captive screw can be locked in place on a parent component without being fastened to a child component. Captive fasteners are typically locked in place using thread locking, press-fitting, or broaching.
Advantages of Using Captive Fasteners
Captive screws help control costs by minimizing damage to machinery from loose screws and by reducing the need for replacement fasteners. Captive screws also help make repairs easier by allowing easy access to components.

Being able to remove components without having to worry about removing the screw as well seems like a really handy option. I bet that a lot of military fasteners have similar options available in order to keep the things that they can do versatile and diverse. Strength would be important in something like this because it would ensure that whatever you attach to it would be strong enough to be held up.
