Abstract: Components of a projectile are held together by a captive collar that is internal to the projectile. The internal captive collar is rotated about a central boss, allowing external threads on the collar to engage one of the mating components and pull that mating component into the other mating component in an axial only translation. The internal captive collar is rotated using a geared-key during assembly. This key engages a geared crown feature of the captive collar, allowing it to rotate. After assembly, the gear key is removed from the assembly. Castellated features nest within slots to transmit torque in the assembled projectile.
