ABSTRACT:
In this blind rivet, the sleeve is counterbored from the rear end, and has interior axial splines forward of the counterbore. The bulb-forming lugs project laterally from a shoulder portion of the mandrel that has a diameter sufficiently great to collapse the sleeve splines during rivet installation. Between the bulb-forming lugs and the mandrel blind end are a set of annular flutes in the mandrel. During rivet installation these flutes urge radial expansion of the sleeve counterbore region to assist hole filling. The sleeve may include a lock-collar-guiding counterbore having an annular convex region providing a locking collar entry resistance surface effective during the initial phase of rivet installation.
