FLOATING CAPTIVE SCREW

摘要

A captive screw for securing together two panels has a screw and a spring extending between the screw head and a ferrule. A collar is formed on the screw shank under the ferrule to limit penetration of the screw threads in a bottom panel so that the upper panel floats on the spring.

主权项

1. A captive screw configured to attach a first panel to a second panel comprising:
a ferrule having a bore; a screw having a head, a shank extending from the head, a threaded portion at an end of the shank opposite the head, and a collar on the shank proximate the threaded portion; and a spring, wherein the shank extends through the bore and the spring, such that the spring is between the ferrule and the head of the screw, wherein the bore includes at least one diameter and the collar includes a maximum diameter, the maximum diameter is greater than the at least one diameter of the bore, and the at least one diameter of the bore is located between the maximum diameter of the collar and the head of the screw, and wherein the collar is configured to limit penetration of the threaded portion into the second panel, so that the first panel, when attached to the ferrule, floats on the spring.
