    • A fastener is provided to having resistance to high temperature and low observability with being exposed to the flow path of gas exhausted from an aircraft engine. A fastener includes a metallic member(80) and a non metallic cap(82). The metallic member includes a shaft(86) having a tip end(88) and a base end(90) between which a screw part(92) is located. The shaft is formed in a body together with a head(94) at the base end. An exemplary head has a lower surface in the shape of a truncated cone(96) and a flat external surface(98) facing the surface. A projection unit(102) is extended from the head in face of the shaft and a base(104) with a relative short diameter and an end(106) with a long diameter. The projection unit is captured on a partition(110) in the cap and pertain the cap in the head for the cap, the head and the projection unit so as to form a stud head. The cap has a radial internal surface(112) engaging with the external surface of the head.
    • 紧固件被设置成具有抵抗高温和低可观察性,并暴露于从飞行器发动机排出的气体的流动路径。 紧固件包括金属构件(80)和非金属帽(82)。 金属构件包括具有尖端(88)的轴(86)和位于其之间的螺纹部分(92)的基端(90)。 轴与头部(94)一起形成在主体中。 示例性头部具有呈锥形(96)形状的下表面和面向该表面的平坦外表面(98)。 投影单元(102)从头部在轴的表面和具有相对较短直径的基部(104)和具有长直径的端部(106)延伸。 投影单元被捕获在盖中的隔板(110)上,并且用于帽,头和投影单元的头部中的盖,以形成螺柱头。 盖具有与头部的外表面接合的径向内表面(112)。
