LUC/LU/U/HU/HUC Standard Face-Mount Joist Hangers

LUC/LU/U/HU/HUC

On This Page

LUCZ — Concealed-flange hanger available for 2x6, 2x8, 2x10 and 2x12 lumber. Ideal for end of ledger/header or post conditions, the LUCZ also provides cleaner lines for exposed conditions such as overhead decks.

LU — Value engineered for strength and economy. Precision-formed — engineered for installation ease and design value.

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.

Material

  • See tables

Finish

  • Galvanized. Some products available in ZMAX® coating.

Installation

  • 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.
  • Joists sloped up to 1/4:12 achieve table loads.
  • For installations 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 carrying member's end grain, the allowable load is adjusted by a factor of 0.67.

Options

  • For both flanges concealed, order HUC.
  • When the HUC is skewed, the header flange opposite the skew direction is not concealed. See image gallery.
  • The HU is available with the A flanges straight at table loads listed.
  • For low-cost, code approved 45° skewed hangers, see SUR/SUL.
  • For field-adjustable hangers, see LSSJ, LRUZ and LSSR.
  • See table-modifications table for available options and associated load capacities for U and HU hangers.
  • For ease of ordering, refer to technical bulletin U/HU Hanger Special Order Worksheet (T-U-HU-WS).
  • LU/LUC cannot be modified.

Product Notes

  • Model configurations may differ from those shown. Some HU models do not have triangle holes. Contact Simpson Strong-Tie.

U/HU/HUC Series Modifications and Associated Load Reduction Factors

U/HU/HUC Series Modifications and Associated Load Reduction Factors
  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.

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
