BLINDBEFESTIGUNGSELEMENT MIT VERFORMBARER TREIBMUTTER UND VERFAHREN ZUR BEFESTIGUNG VON PLATTEN UNTER VERWENDUNG DERSELBEN.
摘要
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.
