The Go/NoGo gauge is used to inspect what specific measurement of rivets?

The Go/NoGo gauge is primarily utilized to inspect the clinch diameter of rivets. This measurement is crucial in ensuring that the rivet has been properly deformed and seated within the materials being fastened, allowing for an optimal load-bearing surface and structural integrity. The clinch diameter is defined as the dimension of the rivet as it spreads and takes on a shape after being installed, and it needs to fall within specific tolerances to guarantee that the rivet is functionally sound and able to meet engineering specifications.

When using a Go/NoGo gauge, the tool will allow the user to determine if the clinch diameter is within acceptable limits (the "Go" aspect) or if it exceeds those limits (the "NoGo" aspect). This binary function is critical in maintaining quality control during the assembly process, ensuring that defective rivet installations are identified and addressed before they can lead to potential failures in the structure.

Other measurements like rivet length, shank diameter, and head thickness, while important in their own right, are typically not evaluated with a Go/NoGo gauge. Instead, they are often measured using calipers or other precision measuring tools, confirming that they meet design specifications but not focusing specifically on the critical
