Simpson Strong-Tie HUC hangers are the concealed flange version of the HU joist hanger. Concealed flange hangers have the face flanges turned in. The Strong-Tie HUC210-4 concealed flange hanger features a G90 Galvanized coating and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153. 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.

• Use all specified fasteners.
• HU/HUC—Can be installed filling round holes only, or filling round and triangle holes for maximum values.
• Joists sloped up to 1/4:12 achieve load tables.
• HU/HUC hangers can be welded to a steel member. Allowable loads are the lesser of the values in the hanger tables or the weld capacity - refer to technical bulletin T-HUHUC-W.

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values
