In rivet terminology, what does 'edge distance' refer to?

Edge distance in rivet terminology specifically refers to the measurement from the center of the rivet to the nearest edge of the material being joined. This measurement is crucial for structural integrity and ensures that the rivet has sufficient support and that the material will not experience premature failure due to tearing or other failures around the rivet.

Accurate edge distance is necessary because it helps prevent issues such as distortion or damage to the materials being fastened, ensuring that the rivet provides adequate holding strength without compromising the surrounding structure. Following proper edge distance guidelines is essential for maintaining the overall strength and effectiveness of the riveted joint, especially in aviation applications where safety and reliability are paramount.
