تعریف و معنای "captive panel screw"

What is a "captive panel screw"?

A captive panel screw is a type of screw designed to fasten a panel or cover while preventing the screw from being fully removed. It has a special design that keeps the screw attached to the panel, so it cannot be lost during removal. Captive panel screws are commonly used in electronics, machinery, and other applications where panels or covers need to be secured but also easily accessible for maintenance or adjustments. These screws provide convenience and ensure the screw stays in place when the panel is removed.
