What tool is used to drive the lockbolt pin into a close tolerance hole?

The lockbolt pin is specifically designed to provide a secure fastening method in aerospace assemblies, and the rivet gun is the tool that is ideally suited for this task. A rivet gun applies controlled force to drive the lockbolt pin into the close tolerance hole, ensuring that it is properly seated and secured. This is critical for maintaining structural integrity in aerospace applications, where even minor imperfections can result in failure.

Using a rivet gun allows for the precise application of pressure needed to ensure that the lockbolt pin expands and locks correctly within the structure, creating a stable and strong joint. Other tools such as drills, screwdrivers, and impact wrenches do not provide the necessary force control or are not designed for fastening processes that require the same level of precision as a rivet gun. Thus, the use of a rivet gun is essential for the proper installation of lockbolt pins in aerospace applications.
