A vehicle includes a composite panel 10 with nonparallel face sheets 12,14, and a reinforcing core 16, preferably honeycomb, lying therebetween. A fastener 30 lies in an aperture 22 of the panel, and includes a socket 32 with a flange 40 bearing against first face sheet 12, and a body 46 defining a
A vehicle includes a composite panel 10 with nonparallel face sheets 12,14, and a reinforcing core 16, preferably honeycomb, lying therebetween. A fastener 30 lies in an aperture 22 of the panel, and includes a socket 32 with a flange 40 bearing against first face sheet 12, and a body 46 defining a through aperture 54 and a spherical cavity 50. Fastener 30 also includes a swivel 34, with a ball-shaped knob 62 rigidly coupled to a post 64. Knob 62 fits into cavity 50 and can swivel. Post 64 is internally and externally threaded. An internally threaded spacer 36 is screwed onto the exterior threads 65 of post 64, to adjust the length of the fastener to the thickness of panel 10. Either post 64 or spacer 36 includes an additional fastening arrangement. In a particular embodiment of the invention, the additional fastening means of the spacer is a flange, and in another embodiment, it is a threaded portion of the bore of the post or of the spacer.
