Transmission Cooler Line help!

[mojoe]

so im working on my 2001 Pontiac sunfire transmission cooler lines, and i busted the bolt off to about 1cm that holds the metal plate in for the cooler lines. does anyone know what that bolt is called? also is that bolt removable ? also this is the cooling line im using http://www.autozone.com/drivetrain/...ion-cooler-line-assembly/566664_555447_0_8069

there is no special name for the bolt, could be 6mm, and there are a number of tools available to remove it such an easy-out.
