The Simpson HSURC410 is a heavy-duty, 45 deg.-skewed concealed flange joist hanger engineered to support 4x10 members in wood construction applications. Skewed right at 45 deg., this hanger features a heavy U-shaped design with concealed header flanges that deliver cleaner, more refined visible lines in exposed conditions - making it an excellent choice where aesthetics matter as much as structural performance. Manufactured from 14-gauge steel with a Zinc Galvanized G90 coating, the HSURC410 provides reliable corrosion resistance and long-term durability in demanding environments.

Key Features

• 45 deg.-skewed right design (HSURC) engineered to support 4x members in wood construction

• Encapsulates the top flange of the joist - no web stiffeners required for standard installation
• Obround nail holes on the acute side allow nails to be easily installed parallel to the joist
• Accommodates a 40 deg.- to 50 deg.-skewed joist for added installation flexibility
• Cannot be modified in the field
• Joist end may be square cut or bevel cut
• 14-gauge steel construction for heavy-duty load performance
• Zinc Galvanized G90 coating for corrosion resistance

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.
