Simpson Strong-Tie 4X8 Galvanized Concealed Flange Face Mount Joist Hanger

Most models have triangle and round holes. To achieve maximum loads, fill both round and triangle holes with common nails. These heavy-duty connectors are designed for schools and other structures requiring additional strength, longevity, and safety factors. Reversed flanges allow you to hang joists and beams flush at corners or any other location where outside flanges will not work. Can be welded to a steel member. 14-gauge galvanized steel.
