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 holeis formed in a cap, and a screw grooveis formed in the hole. The configuration enables the capto be reliably and easily positioned and installed on a fastener memberand reliably prevents the capfrom coming off after the installation thereof. This improves the workability to reduce the production cost while assuring sufficient insulation properties and enables the capto be installed with stable quality irrespective of workers. Preferably, the capis made of a resin in view of mass producibility, weight reduction, and the like.

Lightning-resistant fastener, cap, and method of mounting lightning-resistant fastener

A lightning-resistant fastener, a cap, a fastener member, and a method for attaching the lightning-resistant fastener are provided, which enhance workability and quality stability besides reliably securing an insulating property, and can lead to enhancement in safety of an airframe and reduction in manufacturing cost. A head portionof a fastener main bodyincludes a head cap, and a shaft portionof the fastener main bodyincludes a shaft cap, whereby a direct strike of lightning to a fastener member, and occurrence of an arc discharge from the fastener memberin the case of a lightning strike can be suppressed. A holeis formed in the head cap, and a thread grooveis formed in the hole, whereby the head capcan be reliably and easily positioned and attached to the fastener member
