Abstract
A fastener suitable for use in airplane manufacture or repair that is coated with a pre-mixed moisture cure sealant. The sealant layer is coated with a frangible moisture barrier that will break apart when the fastener is installed, thus exposing the sealant to atmospheric moisture. Once exposed to moisture, the sealant will begin to cure. Preferred embodiments also provide a moisture indicator that provides a visual indication that the outer moisture resistant layer has been damaged.
