To work effectively the captive screw when installed needs to have a space or counterbore between the thread and cover at least equal to the length of the thread.
These are simple but effective when used with our captive screws. The captive screws have a normal thread then a reduced diameter for the rest of the screw length.
The washer has a small length of thread on the internal diameter and once screwed on to the captive screw is effectively captive.
Screw the thin retaining washer onto the captive screw and the screw is therefore retained to the panel
