A self-sealing fixing element is disclosed having a body with a bearing surface, and a bore with an opening in the bearing surface. A curable sealant layer is carried by the bearing surface and encircles the opening in the bearing surface. The curable sealant layer is formed from a sealant material which cures when exposed to atmosphere. A barrier layer overlays the curable sealant layer and can break apart when the fixing element is installed in order to expose the sealant layer to atmosphere. The curable sealant layer has a thickness which decreases away from the bore, and the barrier layer has a thickness which increases away from the bore.
