The Simpson HUC44Z Heavy Face-Mount Concealed-Flange Joist Hanger is a heavy-duty framing connector engineered by Simpson for structures requiring additional strength and safety factors. Designed for nominal 4x4 members, it features concealed header flanges that keep visible lines clean and unobtrusive in exposed framing conditions - making it a practical choice wherever aesthetics matter alongside structural performance. The ZMAX galvanized finish delivers superior corrosion resistance compared to standard galvanized coatings, so the hanger holds up reliably in exterior environments and wherever pressure-treated lumber is used. Formed from 14-gauge steel, this face-mount hanger supports installation to wood, masonry, and concrete headers, giving builders and contractors a versatile solution across a wide range of framing applications.

Key Features

• Concealed header flanges - keep the hanger hidden behind the header for cleaner, more finished-looking visible lines in exposed framing conditions.
• ZMAX galvanized coating - provides extra corrosion resistance beyond standard galvanized finishes, making this hanger a dependable choice for exterior applications and use with treated wood.
• 14-gauge steel construction - delivers the heavy-duty strength needed for structures with higher load and safety factor requirements.
• Extra optional triangle holes - allow additional nailing for increased load capacity when your project demands it.
• Compatible with wood, masonry, and concrete headers - gives builders flexibility to use one hanger across multiple header types and construction scenarios.
• Tested, load rated, and code compliant - the HUC series meets established standards so you can specify and install with confidence on permitted projects.

Why This Product

• Strength built for demanding applications - this hanger is purpose-built for structures requiring additional strength and safety factors, making it a step up from standard joist hangers where higher performance is non-negotiable.
• Cleaner aesthetics without sacrificing performance - the concealed-flange design hides the header connection from view, so exposed timber framing, decks, and interior feature structures look intentional and finished rather than purely utilitarian.
• Corrosion resistance matched to tough environments - ZMAX galvanization is specifically suited for exterior conditions and contact with pressure-treated lumber, helping protect the connection over the long term in high-exposure settings.
• Versatile installation across multiple substrates - whether you are attaching to a wood beam, a masonry wall, or a concrete header, this face-mount hanger accommodates all three, reducing the need to source different products for different parts of a project.

Frequently Asked Questions

What is the nominal joist size this hanger is designed for?

The HUC44Z is designed for a nominal 4x4 member, with a seat width of 3-9/16 inches to accommodate that member size.

What type of fasteners should be used to install the HUC44Z?

Install with 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 3 in. nails in the joist for proper load performance.

Why is the ZMAX coating important on this hanger?

ZMAX galvanization offers extra corrosion resistance compared to standard galvanized finishes, making the HUC44Z suitable for exterior applications and use with treated wood where higher exposure conditions are present.

Are HUC-series hangers code compliant?

Yes. HUC-series hangers are tested, load rated and code compliant, and the HUC44Z also features extra optional triangle holes that allow for additional load capacity when needed.
