Abstract
An apparatus for making and using 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 a moisture source. Once exposed to moisture, the sealant will begin to cure. Preferred embodiments also provide a premature cure indicator that provides a visual indication that the outer moisture resistant layer has been damaged.
