What is the minimum spacing required between rivets for protruding head rivets?

The minimum spacing required between rivets for protruding head rivets is specified as three rivet diameters. This spacing is important to ensure the structural integrity and effectiveness of the riveted joint. Proper spacing helps to distribute the load among the rivets, reducing the risk of overlapping or compromising the strength of the material being joined. When the spacing is adequate, it allows for adequate material around each rivet to maintain strength and to avoid issues such as metal fatigue that could arise from too close an arrangement of rivets. Following this guideline ensures that the rivets function optimally and enhance the durability and performance of the assembly.
