True or False: The head and the collar of a lockbolt fastener must contact the structure at at least one point even if some gap is allowed.

The correct response indicates that the head and the collar of a lockbolt fastener must make contact with the structure at least at one point, even if there is a permissible gap. This principle is crucial for ensuring the integrity and load-bearing capabilities of the fastener in aerospace applications.

Lockbolt fasteners are designed to provide a secure connection between components, relying on the interaction between the head and collar to maintain structural integrity. If there were no contact or if the contact was insufficient, the fastener could fail to properly transmit loads across the joint, potentially leading to catastrophic structural failures. The requirement of at least one point of contact ensures that the fastener can effectively perform its role in the assembly it secures.

In aerospace assembly, stringent standards are mandated for fastener application, and adhering to these regulations is paramount for safety and performance. Recognizing that some gap may be allowed under certain circumstances does not negate the necessity for contact; instead, it highlights the adaptability of fastening techniques while still maintaining fundamental safety standards.
