After seating a Hi-Lok fastener against the assembly, what should you do next?

Seating a Hi-Lok fastener is a crucial step in the assembly process, and once it is properly seated against the assembly, the next step involves installing the collar over the threaded end of the pin. The collar is specifically designed to create a strong and secure joint by locking the pin in place. It ensures that the fastener can bear the necessary loads and maintain the integrity of the assembly.

By installing the collar, you are effectively completing the fastening process. This step is essential in providing the correct amount of tension and preventing the fastener from loosening over time. Proper installation of the collar is critical to achieving the intended performance and safety standards required in aerospace applications.

Removing the fastener or inspecting it for damage at this stage would not be appropriate, as the fastener should already be checked for integrity before seating. Additionally, starting to thread the pin into the assembly should have been completed prior to seating; therefore, the correct action immediately following seating is to install the collar.
