Blind fastener with deformable drive nut and method of fastening panels using same. |
摘要 |
<p>A blind fastener of the type having a fastener body (20) a threaded stem (24) and a sleeve (32) is provided with a deformable drive nut (38) in abutting contact with the fastener body to provide a positive mechanical engagement between the abutting surfaces of the two elements. The underside of the drive nut has an annular ridge (46) made of a deformable material adapted to deform into indentations (44) in the outer surface of the fastener body. The positive mechanical engagement between the two elements minimizes the build-up of tensile load applied to the stem during setting of the fastener.</p> |
