Abstract
A rivet for pivotally interconnecting first and second superposed links each having an opening therethrough, including a first head having a link engaging surface and an outer concave surface, and a shank having first and second portions with a shoulder therebetween, with the first portion being adjacent the head and receivable in the first link opening and the second portion being receivable in the second link opening. During assembly, the rivet is compressed so that the second portion is deformed to form a second head to secure the links between the first and second heads, and the first head is deformed to reduce the concavity of the recess therein and axially shift the first link over the first shank portion to virtually eliminate axial free play.
