A fibrous microencapsulated washer is provided for sealing and retaining a fastener. The fibrous microencapsulated washer includes a substrate and a coating of a microencapsulated material on the substrate. The fibrous microencapsulated washer includes an aperture extending therethrough to receive a fastener, whereby a radial installation of the fastener causes the microencapsulated material to react on the substrate to form a seal and to adhesively secure the fastener to a workpiece.
