ABSTRACT:
The present invention provides a blind bolt fastener having a core bolt. The core bolt has a threaded portion and a non-threaded portion engaging a deformable sleeve and a body. A protrusion extends from the sleeve or the body to engage a groove in the core bolt to prevent axial movement of the core bolt with respect to the body and the sleeve. An optional drive nut is positioned between a head of the body and wrenching flats of the core bolt. The drive nut has protrusions engaging mating members in the head of the body.
