Abstract: A fastener includes a sleeve, a core bolt, and an insert. The sleeve includes a first portion having a first inner diameter, a second portion having a second inner diameter, and a step intermediate the first and second portions. The core bolt includes a cylindrical portion having a first diameter, a threaded portion having a major diameter, and a thread run-out intermediate the cylindrical and threaded portions. The insert is disposed within the sleeve and is sized and shaped to be retained between the step of the sleeve and the thread run-out of the core bolt when the fastener is in a pre-installation position. The fastener compresses the insert between the step of the sleeve and the thread run-out of the core bolt by an installation motion of the core bolt. The insert deforms away from the core bolt to initiate formation of a bulb in response to the compression.

Abstract: A rivet includes a pin member having a head and a lock groove, and a lock ring having a flange. The flange of the lock ring is swaged into the lock groove of the pin member and transformed to a bead that engages the lock groove, and a portion of an outer surface of the lock ring deforms and is rotated inwardly. The rivet is installed within a structure such that the head of the pin member is flush with an outer surface of a panel and the portion of the outer surface of the lock ring is flush with an outer surface of another panel. The pin member includes a frangible portion that breaks off when the rivet is installed.
Abstract translation: 铆钉包括具有头部和锁定槽的销构件以及具有凸缘的锁定环。 锁定环的凸缘被锻造到销构件的锁定槽中并变形成与锁定槽接合的胎圈，并且锁定环的外表面的一部分变形并向内旋转。 铆钉安装在结构内，使得销构件的头部与面板的外表面齐平，并且锁环的外表面的一部分与另一面板的外表面齐平。 销构件包括当安装铆钉时中断的易碎部分。

Abstract translation: 紧固件包括套筒，芯螺栓和插入件。 套筒包括具有第一内径的第一部分，具有第二内径的第二部分和在第一和第二部分之间的台阶。 芯螺栓包括具有第一直径的圆柱形部分，具有大直径的螺纹部分和在圆柱形和螺纹部分之间的螺纹排出。 插入件设置在套筒内，并且当紧固件处于预安装位置时，其尺寸和形状被保持在套筒的台阶与芯螺栓的螺纹流出之间。 紧固件通过芯螺栓的安装运动在套筒的台阶和芯螺栓的螺纹流出之间压入插入件。 插件从芯螺栓变形，以响应于压缩而开始形成灯泡。
