Abstract
A fully retractable captive screw that is low profile, having a snap-in feature allowing for installation of the device into a hole on a panel, by hand, without the need for separate tools. The fully retractable captive screw has a screw, a knob with a screwdriver recess on top, a cylindrical ferrule with attached snap-in mechanism, and a spring that causes the screw to retract into the ferrule when the screw is not engaged.
