Patent number: 8520358Abstract: There are provided a lightning-resistant fastener and a cap, which, while assuring sufficient insulation properties, provide improved workability and highly stable quality to thereby enable a reduction in the manufacturing cost of an airframe, and a method of mounting the lightning-resistant fastener. A hole 32 is formed in a cap 30, and a screw groove 32a is formed in the hole 32. The configuration enables the cap 30 to be reliably and easily positioned and installed on a fastener member 24 and reliably prevents the cap 30 from coming off after the installation thereof. This improves the workability to reduce the production cost while assuring sufficient insulation properties and enables the cap 30 to be installed with stable quality irrespective of workers. Preferably, the cap 30 is made of a resin in view of mass producibility, weight reduction, and the like.Type: GrantFiled: April 2, 2010Date of Patent: August 27, 2013Assignee: Mitbushi Aircraft CorporationInventors: Masahiro Bessho, Wataru Nishimura, Naomoto Ishikawa, Yuichiro Kamino, Toshikatsu Nohara, Toru Hashigami, Tamaki Tsuzuki
