Abstract
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
