The Simpson HUC816 8x16 Concealed-Flange Heavy Face-Mount Hanger is engineered for heavy structural framing connections that demand both additional strength and elevated safety factors. Designed to accept 8x16 dimensional lumber, this face-mount hanger features concealed header flanges that keep visible lines clean and unobtrusive - making it equally at home in exposed timber framing where a finished appearance matters as much as structural integrity. Built in the United States from 14-gauge (68 mil) galvanized steel, the HUC816 delivers the reliability expected in demanding residential and commercial construction applications.

Key Features

• Concealed Header Flanges - Tuck neatly behind the header so hardware stays hidden in exposed timber applications, producing a cleaner, more professional finished look without sacrificing connection strength.
• Heavy-Duty Face-Mount Design - Attaches directly to the face of the carrying member for straightforward installation in large-dimension framing connections requiring additional strength and elevated safety factors.
• 14-Gauge (68 mil) Galvanized Steel Construction - Thick-gauge steel delivers superior load-carrying capability, while the galvanized finish provides resistance to corrosion over the life of the structure.
• 8x16 Lumber Compatibility - Sized specifically to accept 8x16 dimensional lumber, making it a purpose-built solution for heavy timber framing where oversized members are used.
• Made in the United States - Domestic production supports consistent quality standards and reliable availability for contractors and builders.

Why This Product

• Strength Where It Counts - The HUC816 is purpose-built for heavy structural connections, giving builders the confidence of a hanger designed specifically for additional strength and elevated safety factors rather than a scaled-up general-purpose product.
• Aesthetics Without Compromise - The concealed-flange design is a genuine advantage in exposed timber framing, allowing structural hardware to disappear into the connection so the wood remains the visual focus.
• Versatile Configuration Potential - The hanger is available with configurable options including a skewable seat and slope capability up to 45 deg., making it adaptable to non-standard framing conditions beyond straightforward 90-degree connections.
• Trusted Simpson Quality - Produced by Simpson, a name synonymous with structural connectors, the HUC816 carries the brand recognition that builders, engineers, and inspectors rely on for heavy-duty face-mount hanger applications.

Frequently Asked Questions

What size lumber is the HUC816 designed to support?

The HUC816 is sized to accept 8x16 dimensional lumber, making it specifically suited for heavy timber framing connections where large-dimension members are used.

What gauge steel is used in the HUC816, and why does it matter?

The HUC816 is fabricated from 14-gauge (68 mil) galvanized steel. This thick-gauge construction provides superior load-carrying capability compared to lighter-gauge hangers, making it appropriate for structures that require additional strength and elevated safety factors.

What makes the HUC816 suitable for exposed timber applications?

The HUC816 features concealed header flanges, which means the flanges are hidden once installed, resulting in cleaner visible lines. This makes it a practical choice for exposed timber framing where a finished, professional appearance is important alongside structural performance.

How is the HUC816 installed, and does it require special mounting hardware or framing?

The HUC816 uses a face-mount design, meaning it mounts directly to the face of the header. This straightforward installation method does not require the header to be notched or modified to accept concealed flanges, simplifying the framing process on heavy structural connections.
