ABSTRACT:
Blind fastening means for fastening thin materials together without crushing them. Such means comprises a blind rivet sleeve, a blind rivet pin provided with a head to engage the blind end of the sleeve, and spacing means provided intermediate the blind end of the sleeve and the head thereof. As the head of the pin is drawn against the blind end of the sleeve an enlarged blind head forms at the blind side of the materials being fastened while the spacer means engages the interior side of the uppermost of the materials being fastened whereby to prevent crushing of such materials. In one instance the spacer means comprises a spacer sleeve. In a modification the spacer means comprises a second enlarged blind head. The various enlarged blind heads may be achieved in several ways.
