LUC/HUC/HUCQ Concealed Face Mount Joist Hangers – Clean Lines Without Giving Up Strength

When you need a joist hanger that disappears once it's installed, whether for an exposed deck, a stair stringer, or any spot where face-mount flanges would show, this concealed-flange family covers light duty through the heaviest loads. LUC, HUC, and HUCQ all hide their flanges behind the joist for a clean look. The difference between them is capacity and how they fasten.

LUC, HUC, and HUCQ: What's the Difference?

  • LUC is the light-duty option, sized for 2x6 through 2x12 solid sawn lumber. It's built for end-of-ledger, header, and post conditions where you want a clean look, like an overhead deck, without needing heavy-duty capacity.
  • HUC is the concealed-flange version of the HU hanger: heavy duty, with round and triangle nail holes so you can fill round holes for standard capacity or both for maximum rated load. Like HU, it covers solid sawn lumber, I-joists, glulam, and SCL depending on the size.
  • HUCQ steps up further, installing with Strong-Drive SDS screws (supplied with the hanger) instead of nails for higher capacity and a faster install. Select HUCQ models also carry an F/T fire-resistance rating, worth checking if your project has a fire-rated assembly requirement.

Key Features & Benefits:

  • Concealed Flange Design: Hides fasteners and flanges behind the joist for a clean, finished look.
  • LUC for Light Duty: Sized for standard 2x6-2x12 solid sawn framing.
  • HUC Flexibility: Round and triangle nail holes for standard or maximum rated capacity.
  • HUCQ High Capacity: SDS screw installation for higher loads and faster fastening; select sizes are fire-rated.
  • Broad Compatibility: Solid sawn dimensional lumber, I-joists, glulam, and SCL, depending on size.
  • Finish Options: G90 galvanized standard, with ZMAX and stainless steel available on select sizes.

Installation Guide for LUC/HUC/HUCQ Hangers

  1. Position the hanger flush against the header or beam, with the flange side facing away from view.
  2. Fasten the hanger to the header. LUC and HUC use nails; HUCQ uses the Strong-Drive SDS screws supplied with the hanger.
  3. Set the joist into the hanger and fasten through the joist.
  4. For HUC hangers rated for maximum load, fill both the round and triangle holes.

Find the Right Hanger for Your Project

Need a concealed look for a light-duty ledger or deck post condition? LUC is usually the right fit. Carrying an I-joist, SCL, or a heavier load and still want the flanges hidden? Step up to HUC, or HUCQ if you want screw installation and the option of a fire rating. Don't need the concealed flange? Our HU/HUS Heavy Duty and LUS/LU/U Light Duty hangers cover the same range with exposed flanges. Browse our full lineup of Simpson Joist Hangers to compare every option.
