Abstract
A blind rivet assembly includes a mandrel having a male threaded portion at its distal end to be screwed into an internal female threaded portion of a rivet body. The mandrel has a section of enlarged diameter adjacent the male threaded portion joined by a breaker groove to a pulling portion. The section of enlarged diameter is accommodated within an internal bore of the collapsing portion of the rivet body, the collapsing portion having a radial groove on the outer surface thereof for improving the radial expansion of the rivet when installed. A shoulder in the internal bore supports a sealing ring. When assembled correctly, the pulling portion breaks off at the breaker groove.
