Lockbolts are identified by their grip what?

Lockbolts are identified by their grip length, which refers to the distance from the underside of the head of the lockbolt to the end of the bolt before any threads. This measurement is crucial in ensuring that the lockbolt will fit correctly into the assembly being fastened. The grip length must match the thickness of the materials being joined to ensure that the lockbolt can provide the necessary clamping force for a secure connection.

In aerospace applications, where precision and safety are paramount, selecting the correct grip length is essential for maintaining structural integrity. If the grip length is too short or too long, it can lead to insufficient engagement of the bolt, weakening the connection and potentially compromising the assembly's performance.

Other dimensions, such as width, diameter, and thickness, do not define how well a lockbolt will perform in its intended application as grip length does. Therefore, understanding grip length is vital for anyone working with lockbolts in aerospace assembly.
