What is used on the mobile aircraft arresting system to ensure a 3/8 inch clearance gap between the bolt head and anchor plate?

The taper bolt gauge is specifically designed to measure the gap between the bolt head and anchor plate, ensuring that the required 3/8 inch clearance is achieved in the mobile aircraft arresting system. This gauge is shaped to fit securely around the bolt, allowing for precise measurements that are essential for the system’s functionality and safety. Accurate gap measurement is critical as it can affect the performance of the arresting system during aircraft landings, influencing its ability to safely stop aircraft.

In contrast, depth gauges primarily measure depths rather than specific clearances or gaps, while a locking mechanism usually secures components in place but does not measure distance. Spacer blocks can be used in some applications to create space, but they do not provide the precision measurement necessary in this context. Hence, the taper bolt gauge is the appropriate tool for this specific task.
