In sheet metal work, what is the term for the distance from the edge of a piece to the center of a rivet hole?

The correct term for the distance from the edge of a piece to the center of a rivet hole is "edge distance." This measurement is crucial in sheet metal work because it ensures structural integrity and prevents issues such as tearing or excessive stress concentration around the rivet. Proper edge distance is necessary to ensure that the rivet has enough material around it to hold securely without compromising the strength of the sheet metal, as well as to allow for any tolerances in manufacturing or assembly.

Rivet spacing refers to the distance between the centers of adjacent rivet holes along the joint line, which is a different consideration in the layout of rivets. Joint clearance pertains to the space required between parts that are to be fastened together, which is also distinct from the measurement of edge distance. Setback, on the other hand, is related to the distance that rivet holes are set back from the edge of the joint, but it does not specifically refer to the distance from the edge to the center of the rivet hole. Understanding these terms helps in effective design and execution in sheet metal fabrication.
