Abstract
A joint is formed in a stack of at least two sheets of light metal alloy, using a self-piercing rivet that is fully hollow. The rivet is coated at least along a portion of its bore by a lubricant and pierces the upper surface thereof and such that the shank deforms outwardly to interlock with the materials but without penetration to the die side of the material. The outside diameter of the shank of the rivet is 5.4 mm or less. The die has a volume that is less than 60% or 70% of the effective solid volume of the rivet.
