Captive screw

A fastener connects panel members in a flush position. The fastener includes a pair of connecting members which are snap-fit within apertures provided within each of the panel members for securing the panel members together. The fastener also disconnects the panel members when secured together. For this purpose, at least one of the connecting members is removable from the panel member aperture to disconnect the panel members. The fastener allows the panels to be assembled together and disassembled quickly and with little or no tooling.

An adjustable draw latch of the over-center type for latching two closure members has a tension-link cover which is detachably secured pivotally at one end to a keeper mounted on one of the closure members. The cover is secured pivotally at its other end to one end of an adjustable compression link. The other end of the compression link is pivotally attached to a base bracket mounted on the other closure member. The adjustable compression link includes an internally threaded nut which is pivotal within the base bracket, and a T-shaped member having an a cross head of cylindrical shape and an externally threaded stud which extends from the cross head at right angles thereto and is threaded into the pivot nut. The cross head is pivotally secured within the cover at one end thereof. The cover provides a bearing surface for the cross head.

A tamper-resistant fastener is disclosed, having a head which tends to prevent the removal of the fastener by conventional tools. The fastener head is provided with three sockets, at least one of which is eccentrically disposed with respect to the other two. The fastener may be attached and removed only with the application of a special driving tool having a male portion adapted for matable engagement with the fastener head. The eccentricity of at least one of the sockets permits the turning of the fastener upon the application of torque by the driving tool. The three-socket arrangement substantially eliminates the tendency of the driving tool to tilt when torque is applied.
