True or False: To ensure acceptable lockbolt installation, the sum of all gaps must be less than the value in the engineering specification table.

In the context of lockbolt installation, the requirement that the sum of all gaps must be less than the specified value in the engineering specification table is crucial for ensuring the effectiveness and reliability of the joint. The engineering specifications provide tolerances and limits that account for several factors, including the material properties and the load distribution in the assembly.

If the sum of all gaps exceeds the specified value, it can lead to insufficient clamping force, which may compromise the integrity of the fastening. A proper installation ensures that the lockbolts can perform their intended function of maintaining structural integrity under load, allowing for optimized performance and safety.

Thus, the statement is true because following these engineering specifications ensures that the installation meets the necessary performance criteria outlined in the design documents. This principle applies universally, rather than being restricted to specific fasteners or varying based on installation conditions.
