When determining the clinch thickness, if the driven head's clinch thickness exceeds gauge thickness, how is this evaluated?

The evaluation of clinch thickness in relation to the gauge thickness is crucial in ensuring that the assembly meets structural integrity and design requirements. When the driven head's clinch thickness exceeds the gauge thickness, it indicates that the fastening process is producing a strong joint that is likely more secure than a joint that only meets the gauge.

In aerospace applications, achieving a clinch thickness that exceeds the minimum gauge thickness is typically deemed acceptable because it can enhance the overall strength and durability of the assembly. Therefore, having greater thickness can serve as a safety buffer against failure under load or stress, which is particularly important in the aerospace industry where safety and reliability are paramount.

This understanding supports the conclusion that such a scenario—where the clinch thickness exceeds the gauge thickness—is advantageous and evaluates as acceptable according to aerospace assembly standards.
