FASTENER AND METHOD OF INSTALLING SAME

摘要

A fastener includes a body having deformable first end, a second end, and a passage extending through the body between the first and second ends. The fastener further includes a corebolt having first and second ends and a region of reduced diameter disposed between the first and second ends and a sleeve having first and second ends, the second end having a bulbing portion. The corebolt is disposed within the sleeve and the body with the first end of the corebolt in engagement with the first end of the sleeve and the first end of the body disposed adjacent the second end of the sleeve. The bulbing portion is adapted to form an enlarged blind head when the corebolt is rotated in relation to the sleeve. The first end of the body is adapted to deform radially inwardly into the region of reduced diameter.

1. A fastener comprising:
a body having a first end, a second end, and a passage extending through the body between the first and second ends; a corebolt having first and second ends and a region of reduced diameter disposed between the first and second ends; a sleeve having first and second ends, the second end having a bulbing portion; and a tapered ramp disposed at the first end of the body; wherein the corebolt is disposed within the sleeve and the body with the first end of the corebolt in engagement with the first end of the sleeve and the tapered ramp disposed adjacent the second end of the sleeve; and wherein the bulbing portion is adapted to form an enlarged blind head when the corebolt is rotated in relation to the sleeve; wherein the tapered ramp is adapted to deform radially inwardly into the region of reduced diameter to allow movement of the blind head along the body.
