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.

Abstract: A device for screwing-in and setting self-drilling blind rivets in a structure, has a clamping unit with two clamping jaws for holding a spindle of a rivet inserted therebetween. The jaws are guided in complementary grooves provided in a retaining unit which is installed in a tubular housing. A cover cap is inserted in the housing for limiting a displacement path of the retaining unit and the clamping jaws in a direction of a central axis of the retaining unit. A shaft to be connected to a driving unit for driving the screwing-in and setting device is inserted in the retaining unit. The shaft acts on a spring-loaded support having radially protruding bolts slidable in longitudinal slits provided in the housing. A displacement path of the retaining unit in the direction towards a free end of the housing is longer than that of the clamping laws.
