1. A system for use in covering a portion of a fastener protruding from a surface, the system comprising: a cap that comprises: an interior surface;a base that at least partially delimits the interior surface; andpawls extending from the interior surface, each of the pawls comprising a first end proximate to the interior surface, and a second end distal from the interior surface, wherein the second ends of all the pawls are equidistant from the base; anda nut configured to be coupled to the fastener and comprising a tooth, wherein the pawls are configured to engage the tooth. 2. The system in accordance with claim 1, wherein the nut is configured to threadably engage the fastener. 3. The system in accordance with claim 1, wherein, when the pawls engage the tooth, the pawls are loaded in compression against the tooth. 4. The system in accordance with claim 1, wherein the cap further comprises a seal coupled to the base to engage the surface. 5. The system in accordance with claim 4, wherein the seal is configured to bias the pawls against the tooth. 6. The system in accordance with claim 1, wherein the cap further comprises: a wall comprising the interior surface; andat least one port that extends through the wall. 7. The system in accordance with claim 6, wherein the at least one port comprises an injection port configured to receive sealant therethrough and a bleed port configured to allow air to escape from the interior. 8. The system in accordance with claim 1, wherein the tooth is delimited on one side by a groove formed in an outer surface of the nut. 9. The system in accordance with claim 1, wherein the nut is configured to be coupled to the fastener with an interference fit. 10. The system in accordance with claim 1, wherein the tooth and the surface are separated by a space. 11. The system in accordance with claim 1, wherein each of the pawls comprises a first end proximal to the base, and a second end distal from the base, wherein the second ends of the pawls are configured to engage the tooth. 12. The system in accordance with claim 11, wherein the second end has a greater width than the first end. 13. The system in accordance with claim 1, wherein the tooth includes a tapered surface facing away from a head of the fastener. 14. A system for use in covering a portion of a fastener protruding from a surface, the system comprising: a cap that comprises: an interior;a base that at least partially delimits the interior; andpawls on the interior;a collar configured to be coupled to the fastener and comprising a tooth, wherein the pawls are configured to engage the tooth in tension; anda retainer configured to couple the collar to the fastener. 15. The system in accordance with claim 14, wherein each of the pawls comprises a first end proximal to the base, and a second end distal from the base, wherein the first ends of the pawls are configured to engage the tooth. 16. The system in accordance with claim 15, wherein the first ends of the pawls are positioned in a space between the tooth and the surface when engaged with the tooth. 17. The system in accordance with claim 14, wherein, when the pawls engage the tooth, the pawls are loaded in tension. 18. The system in accordance with claim 14, wherein the cap further comprises a seal coupled to the base to engage the surface. 19. The system in accordance with claim 18, wherein the seal is configured to bias the pawls against the tooth. 20. The system in accordance with claim 14, wherein the cap further comprises: a wall comprising the interior surface; andat least one port that extends through the wall.
