To remove the collar, the Hi-Lok collar pliers should be placed against the __________ of the Hi-Lok collar.

The Hi-Lok collar pliers are specifically designed to engage effectively with the base of the Hi-Lok collar. When applying these pliers, positioning them at the base allows for a secure grip and maximizes leverage, which is essential for safely and efficiently removing the collar. This technique minimizes the risk of damaging the collar or the surrounding components during the removal process, ensuring proper operation and maintenance of the fastening system.

Other placements, such as using the top, side, or middle of the collar, do not provide the same level of control and power needed, potentially leading to inefficient removal and possible complications in the assembly process. Identifying the correct placement is crucial for any mechanic to ensure reliability and effectiveness in aerospace assembly tasks.
