Fastener assembly and connector device for interconnecting multiple objects

A method of securing a flanged joint, the method comprising:

• providing a first fastener assembly and a second fastener assembly interconnected by a tether, each fastener assembly comprising a central body having a substantially cylindrical cross-section, a pair of radial lips extending outward from the central body, a pair of hex engagement portions extending axially outward from respective radial lips and having hexagonal outer profiles, a threaded bore extending through a full axial length thereof, and an annular channel defined between the respective radial lips around the central body within which the tether is tied;
• positioning a first bolt through a bolt hole in a flange from a first side thereof;
• threading the first bolt into the threaded bore of the first fastener assembly disposed on a second side of the flange opposite the first side;
• positioning a second bolt through a bolt hole in the flange;
• and threading the second bolt into the threaded bore of the second fastener assembly;
• wherein the tether maintains the first fastener assembly and the second fastener assembly in connected relation throughout the method.
