Abstract
A self-drilling blind tension rivet has a sleeve with a stop flange and a rivet shank and having at one end a drilling unit and at the other end a flattened section for engagement with a rotation and tension applying tool for drilling in and setting the blind tension rivet. The flattened section which extends over the major part of the length of the shank has roughened surfaces formed by transverse ribs and is limited by two elongated portions protruding radially beyond the outer diameter of a cylindrical part of the shank.
