First claim
Opening claim text (preview).
What is claimed is: 1. A fastener comprising: a fastener body comprising a shaft and a head; and a portion of polyether ether ketone connected to said head of said fastener body, said polyether ether ketone having a crystallinity of at most 5 percent. 2. The fastener of claim 1 wherein said polyether ether ketone has a crystallinity of at most about 2 percent. 3. The fastener of claim 1 wherein said polyether ether ketone has a crystallinity of at most about 1 percent. 4. The fastener of claim 1 wherein said polyether ether ketone has a crystallinity of about 0 percent. 5. The fastener of claim 1 wherein said fastener body is formed from a metallic material. 6. The fastener of claim 1 wherein said fastener body comprises titanium. 7. The fastener of claim 1 wherein said portion is connected to a top of said head. 8. The fastener of claim 1 wherein said shaft is threaded. 9. The fastener of claim 1 wherein said head comprises at least one engagement feature. 10. The fastener of claim 9 wherein said engagement feature comprises an undercut protrusion. 11. The fastener of claim 9 wherein said engagement feature comprises a roughed surface. 12. The fastener of claim 1 further comprising at least one tie layer positioned between said fastener body and said portion of polyether ether ketone. 13. An aircraft comprising the fastener of claim 1 . 14. A fastener comprising: a fastener body comprising polyether ether ketone having a crystallinity of at most 5 percent. 15. The fastener of claim 14 wherein said polyether ether ketone has a crystallinity of at most about 2 percent. 16. The fastener of claim 14 wherein said polyether ether ketone has a crystallinity of at most about 1 percent. 17. The fastener of claim 14 wherein said polyether ether ketone has a crystallinity of about 0 percent. 18. The fastener of claim 14 wherein said fastener body comprises a shaft and a head. 19. The fastener of claim 18 wherein said polyether ether ketone has a crystallinity of at most about 2 percent. 20. An aircraft comprising the fastener of claim 14 .
