What does the pin protrusion measure in a Hi-Lok?

In a Hi-Lok assembly, the pin protrusion specifically measures the distance the pin extends out from the surface of the structure. This measurement is critical as it ensures that the pin is properly engaged and secured within the collar, allowing the joint to maintain its integrity under various loads. The correct amount of pin protrusion is essential for the functionality and safety of the assembly, as it provides the necessary clamping force when the collar is tightened. Understanding this measurement helps technicians identify whether the pin has been installed correctly and can contribute to the overall effectiveness of the fastened joint.
