U/HU/HUC/HUCQ Face-Mount Hangers


On This Page

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.

HUCQ — Features concealed flanges so it can be installed close to the end of the supporting beam or on a post. They install with Strong-Drive® SDS Heavy-Duty Connector screws (supplied with the hanger) for high capacity and ease of installation.


  • U — 16 gauge; HU/HUC/HUCQ — 14 gauge


  • Galvanized


  • 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.
  • HU/HUC/HUCQ 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.


  • Order HUC_X hanger. For both flanges concealed, order HUC.

Sloped, Skewed and Sloped/Skewed:

  • For low-cost, code-approved 45° skewed hangers, see SUR/SUL.
  • For field-adjustable hangers, see LSSR.
  • See modification table for available options and associated load capacities for U and HU hangers.
  • HUCQ cannot be modified.

See Face Mount Hanger tables.

See Hanger Options for hanger modifications, which may result in reduced loads.

U/HU/HUC Series Modifications and Associated Load Reductions

U/HU/HUC Series Modifications and Associated Load Reductions
  1. Modified seat is sloped, skewed, or both. If sloped only or skewed only, use a smooth-shank stainless-steel reduction of 0.65.
  2. For hanger applications with both flanges concealed, W must be at least 2 5/16". To order, ask for HUCXXX. For skewed HUC, only flange on acute side is concealed.
  3. Skews over 50° require a square-cut joist.
Reduction Factor Instructions

Allowable Download = Seat x Flange x Stainless Steel Nails x Other Fastener Substitutions x (Table Load)
Allowable Uplift =
  0.75 x Face Fastener Type x (Table Load) for skewed or sloped
  1.00 x Face Fastener Type x (Table Load) for non-skewed or non-sloped
