ABSTRACT:
An expandable sealant is provided for a fastener including a threaded defining surface. The fastener includes the expandable sealant as a coating adhered to at least a portion of the thread-defining surface to lock the fastener in place and to expand to fill space between the thread-defining surface of the fastener and an aperture through which the fastener is passed to seal the aperture to prevent fluid and gases from passing therethrough.
