Captive screw

A captive screw for releasably securing a closure member in a closed position, the closure member having at least one hole, the captive screw comprising:

• a ferrule having a first end, a second end, and a hollow bore, said first end of said ferrule being adapted for engaging the at least one hole in the closure member;
• and
• a screw having a head and a shaft, said shaft having a threaded portion, said screw having a flange on said shaft, said flange being spaced apart from said head, said flange being captured within said bore of said ferrule such that said screw can be moved axially relative to said ferrule, said threaded portion of said shaft projecting from said ferrule to varying amounts responsive to movement of said flange within said bore of said ferrule over at least a portion of a range of movement of said flange within said bore of said ferrule.
