    • A lockbolt (100, 200, 300) which includes a head portion (102) and a shaft (104, 302) which extends from the head portion (102). The shaft (104) includes at least a portion which is threaded and has a multi-lobular profile. A collar (120, 304) is swageable onto the multi-lobular threaded portion (104), and thereafter the lobes (114) provide that the collar (120, 304) does not tend to vibrate loose from the threading. The fact that the section which has a multi-lobular profile is also threaded provides that the collar (120, 304) (or a conventional threaded nut) can be selectively rotatably removed and re-installed on the lockbolt (100, 200, 300). Before swaging, the collar (120, 304) may initially include a cylindrical bore (130), or a bore (130) which is multi-faceted, preferably generally corresponding to the profile of the multi-lobular portion of the lockbolt (100, 200, 300). The lockbolt (100, 200) may include a frangible pintail (106, 202), wherein the multi-lobular threaded portion is disposed between the head portion of the bolt and the frangible pintail. Alternatively, the lockbolt (300) maybe pintail-less. A tool (310) for swagging a collar (304) onto a pintail-less lockbolt (300) is also described.

    • A device for positioning a threaded nut relative to an aperture in a component for attachment of a threaded bolt comprising a cage having a nut receiving part and a pair of tongues extending from the cage and locatable relative to the aperture to hold the nut over the aperture, an inwards protrusion on one or both of the tongues for retaining the nut in the cage, one or both of the tongues being resiliently deformable such that, in use, they deform to allow travel of the nut out of the cage, past the inwards protrusion and towards the component when the nut is threaded on to the bolt.
    • 一种用于相对于用于连接螺纹螺栓的部件中的孔定位螺母的装置,该装置包括具有螺母接收部分和从该保持器延伸并可相对于该孔定位以将螺母保持在该孔上的一对舌片的保持架 ,一个或两个舌片上的向内突起用于将螺母保持在笼中,一个或两个舌片可弹性变形,使得它们在使用中变形以允许螺母从笼中移出,越过内部 当螺母拧到螺栓上时突出并朝向部件。
