High-performance blind rivet particularly for structural attachment

A blind rivet comprising:

• a hollow sleeve;
• a crimping ring;
• and
• a mandrel, received by the hollow sleeve and by the crimping ring, the mandrel comprising:
• at a first end, a head configured to bear against the sleeve,
• at a second end, a shank configured to receive a traction load from a tool,
• a breaking groove which breaks off when the traction load reaches a certain value, the breaking groove including a breaking groove bottom, a first breaking-groove-side extending from the breaking groove bottom toward the shank, a second breaking-groove-side extending from the breaking groove bottom towards the head, the first breaking-groove-side and a central axis of the mandrel defining a first angle, the second breaking-groove-side and the central axis defining a second angle, the second angle being greater than the first angle, and
• an embrittlement groove contiguous with the first breaking-groove-side, wherein
• the shank is preformed with a plurality of crimping grooves and is dimensioned in such a way that once the shank is broken off on the breaking groove, a portion of the crimping grooves extend beyond the sleeve, and
• the crimping ring is configured to crimp on the crimping grooves extending beyond the sleeve.
