The Simpson HSURC410 4x10 Concealed Flange Joist Hanger Skewed Right is a heavy-duty connector engineered to support 4x10 lumber members in wood-framed construction where a 45 deg. skewed right connection is required. Its heavy U-shaped body pairs concealed header flanges with a turned-in A2 (acute) flange, making it equally suited to structural end-of-wall installations and exposed framing conditions where clean, refined visible lines matter. Built to 14-gauge steel with a Zinc Galvanized G90 coating, this hanger delivers the corrosion resistance and long-term durability that demanding framing applications demand.

Key Features

• 45 deg. skewed right orientation with a 40 deg. - 50 deg. accommodation range - gives installers meaningful angular flexibility around the nominal skew angle, reducing the need for precise cuts and saving time on the job site.
• Concealed header flanges - tuck behind the header for a cleaner, more refined appearance in exposed framing conditions where visible hardware would detract from the finished look.
• Turned-in A2 (acute) flange - enables straightforward end-of-wall installation without requiring additional blocking or complex modifications to the framing layout.
• Square-cut or bevel-cut joist end compatibility - eliminates the mandatory bevel cut required by many skewed hangers, giving framers the option to work with square-cut members and reduce material waste.
• 14-gauge steel construction with Zinc Galvanized G90 coating - provides a heavy-duty structural foundation combined with corrosion resistance suited to environments where long-term performance is critical.
• Compatible with #9 x 2-1/2 in. Strong-Drive SD Connector Screws or 0.162 in. x 3-1/2 in. nails - supports common fastener types already found on most job sites, allowing installers to use whichever fastening method fits their workflow.

Why This Product

• Structural performance meets clean aesthetics - the concealed flange design handles the load demands of supporting 4x10 members while keeping header hardware out of sight, making this hanger a practical choice for exposed architectural framing where appearance and strength both matter.
• Built-in installation flexibility - acceptance of joists skewed anywhere from 40 deg. to 50 deg. and compatibility with both square-cut and bevel-cut joist ends means fewer field adjustments and a more forgiving installation process compared to hangers with rigid angle requirements.
• Domestic manufacturing from Simpson - the HSURC410 is a product of United States manufacturing, supporting consistent quality control and reliable availability for contractors and builders who depend on it.
• Designed specifically for 4x10 framing members - purpose-built sizing ensures a proper fit without shimming or improvising, which protects structural integrity and keeps installations code-compliant and inspection-ready.

• 0.162" x 3-1/2" Nails

Frequently Asked Questions

What joist size is the HSURC410 designed to support?

The HSURC410 is engineered specifically to support 4x10 lumber members in wood construction applications.

Does this hanger work if the joist is not cut at exactly 45 deg.?

Yes. The HSURC410 accommodates a 40 deg.- to 50 deg.-skewed joist, providing a range of installation flexibility around the nominal 45 deg. skew angle. The joist end may also be either square cut or bevel cut.

Why choose a concealed flange hanger over a standard hanger in exposed applications?

The concealed header flanges on the HSURC410 keep the mounting hardware hidden from view, delivering cleaner and more refined visible lines. This makes it a strong choice for exposed construction conditions where aesthetics matter alongside structural performance.

Are web stiffeners required when installing the HSURC410?

No. The HSURC410 encapsulates the top flange of the joist, so web stiffeners are not required for a standard installation.
