To provide a simple fastener assembly isolated from torque application during assembly and disassembly.
A fastener for securing a composite panel 14 to a noncomposite support 12 includes a composite stud 22 with a notched shank 26, and a collar 36 with an axis 38 and circumferentially extending ribs 56. When assembled, the ribs 56 and notches 28 engage each other to resist axial translation between the stud and the collar. In one embodiment, a spring 66 urges the rib 56 into contact with the notch 28 to tension the stud and clamp the panel to its support. In a second embodiment, the collar 36a has external threads. A nut 76 engages the threads to tension the stud and clamp the panel to its support. The spring 66 is optional in the second embodiment. Because the composite stud is susceptible to damage if exposed to excessive torque, both embodiments include features to minimize torque transfer to the stud during assembly and disassembly.
