An adhesive composition ("composition") comprises an epoxy resin, a binder, and a curing agent. Typically, the composition further comprises an aqueous solvent (e.g. water) such that the composition can be referred to as an aqueous adhesive composition. The epoxy resin is typically encapsulated to prevent premature cure of the composition. After rupture of the encapsulated epoxy resin, the composition cures to form an adhesive. The composition is useful for articles such as fasteners (e.g. nuts and bolts) such that it can be referred to as a fastener adhesive. Typically, the composition is disposed on a threaded surface of the fastener. The fastener can be used for an assembly in which the composition generally cures after installation of the fastener. To make the fastener, the adhesive composition can be applied on the threaded surface. After application, the composition can be dried in instances where the composition still includes the aqueous solvent.
