No more fumbling with G-clamps, pop rivets and extra pairs of hands. This sheet metal holding system quickly and easily clamps lap jointed panels together before final welding, bonding, or riveting. The blind fasteners have an expanding pin which, when inserted through an 3/16" hole in your job and released, exerts over 18lbs. holding pressure. Installation pliers overcome the powerful spring pressure. Start with a kit, and then build it up by ordering extra fasteners as you need them. Originally designed for assembling aircraft skins, this is the best fastening system we have seen.
