U3516/20 Standard Joist Hanger
U — The standard U hanger provides flexibility of joist to header installation. Versatile fastener selection with tested allowable loads.
HU/HUC — 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.
HUCQ — Features concealed flanges so it can be installed close to the end of the supporting beam or on a post. They install with Simpson Strong-Tie® Strong-Drive® SDS Heavy-Duty Connector screws (supplied with the hanger) for high capacity and ease of installation.
See Face-Mount Hanger Load Tables
Use all specified fasteners; see General Notes.
HU/HUC — Can be installed filling round holes only, or filling round and triangle holes for maximum values.
HUCQ — When using structural composite lumber columns, the capacities shown in the tables are for fasteners applied to the wide face of the column.
Web stiffeners are required for all I-joists used with these hangers.
For installation to masonry or concrete, see HU/HUC/HSUR/L.
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 HU/HUC Welded Onto Steel Members (T-HUHUC-W).
When nailing into a carrying member's end grain, the allowable load is adjusted by a factor of 0.67.
For welding information, see technical bulletin T-HUHUC-W.
Order HUC_X hanger. For both flanges concealed, order HUC.
