The Simpson Concealed-Flange Heavy Face-Mount Hanger HUC5.31/14 is an engineered structural connector from Simpson designed for heavy-duty face-mount joist and beam connections where both load performance and clean visual presentation matter. Built for structural framing assemblies that require additional strength and elevated safety factors, this heavy concealed-flange hanger suits a wide range of residential and commercial wood-framed construction applications - from load-bearing interior connections to exposed architectural framing where visible hardware is undesirable.

Key Features

• Concealed Header Flanges - flanges are hidden from the header face, delivering cleaner visible lines in exposed or architectural framing conditions where appearance is as important as structural integrity.
• Heavy-Duty 14 ga. (68 mil) Steel Construction - the heavier gauge provides additional strength and elevated safety factors compared to lighter-gauge hangers, making this connector well suited for demanding load-bearing connections.
• Galvanized Finish - provides corrosion resistance to help protect the connector's structural integrity over the life of the assembly.
• Face-Mount Installation - attaches directly to the header face, simplifying installation in joist and beam connections across a broad range of structural framing configurations.
• Configurable Options Available - models can be configured with a skewable seat or a sloping seat up to 45 deg., adding flexibility for non-standard framing conditions without sourcing a separate product.

Why This Product

• Strength Where Standard Hangers Fall Short - the HUC5.31/14 is purpose-built for applications demanding additional strength and elevated safety factors, making it a reliable choice when a standard-gauge hanger is not sufficient for the load or application.
• Architectural Appeal in Exposed Framing - the concealed-flange design eliminates visible hardware on the header face, allowing contractors and designers to use a structural connector without compromising the look of finished or exposed framing.
• Versatile Across Residential and Commercial Projects - approved for face-mount joist and beam connections in both residential and commercial wood-framed construction, this hanger adapts to a wide range of structural framing assemblies in a single product.
• Domestic Craftsmanship from Simpson - produced in the United States by Simpson, a trusted name in structural connectors, this hanger is engineered and fabricated to meet demanding construction requirements.

Frequently Asked Questions

What makes the HUC5.31/14 different from a standard joist hanger?

The HUC5.31/14 is a heavy-duty hanger built from 14 ga. (68 mil) steel, which provides additional strength and elevated safety factors compared to lighter-gauge standard hangers. It also features concealed header flanges, which eliminate visible hardware on the header face - a distinction that matters in exposed or architectural framing conditions where appearance is a consideration.

Is this hanger suitable for exposed framing applications?

Yes. The concealed header flange design is specifically intended for use in exposed framing conditions. Because the flanges are hidden against the header rather than wrapping visibly around it, the installed result presents cleaner, more unobtrusive visible lines suited to finished or architectural assemblies.

What finish does the HUC5.31/14 have, and what environments is it appropriate for?

The HUC5.31/14 has a galvanized finish, which provides corrosion resistance suitable for a variety of interior and protected exterior structural applications.

How is the HUC5.31/14 installed?

The HUC5.31/14 uses a face-mount design, meaning it attaches directly to the face of the header or beam. This approach simplifies installation across a wide range of framing configurations without requiring the hanger to wrap around or be recessed into the supporting member.
