The Sonar Metal Assembly Screws are used for attaching various accessories, such as lift bag pouches, suit inflation mounting systems and sidemount buttplates, to an OMS IQ Pack or Dive Rite TransPac harness, or to a hard backplate. Designed to fit through a 3/8-inch hole, the metal bookscrews include O-rings to help keep the screw in place.
These two-part book screws are made from marine grade, chrome-plated brass. Sold as a set of two.
Note: We do NOT recommend using these deadbolts to secure wings to backplates. The metal screws will scratch your tank, so instead use the plastic versions.
