The Simpson 4x6 Concealed Flange Joist Hanger Skewed Right ZMAX HSURC46Z is a heavy-duty, 45 deg.-skewed right hanger engineered to connect 4x6 lumber members at a precise angled joint in wood-framed construction. Its concealed flange design keeps structural hardware out of sight, making it well suited for deck framing, floor systems, and any application where a clean appearance matters as much as structural performance. Fabricated at 14 gauge with a ZMAX coating, this hanger is built to handle demanding conditions while delivering a secure, code-compliant connection.

Key Features

• 45 deg. skewed right orientation - positions the 4x6 joist at the correct angle to the header without cutting, bending, or modifying the hanger, saving time and reducing on-site fabrication errors.
• Accommodates 40 deg. to 50 deg. skew angles - provides a practical tolerance window so framers are not locked into a single exact angle, improving fit across real-world framing conditions.
• Concealed flange design - tucks the header flange out of view for a finished, professional appearance in exposed framing situations such as open deck structures or visible floor systems.
• 14-gauge steel construction - delivers the structural thickness needed for heavy load transfer at skewed joist connections without requiring web stiffeners under standard installation conditions.
• ZMAX coating - provides a higher level of corrosion resistance compared to standard galvanized finishes, making this hanger appropriate for exterior and treated-lumber applications.
• Accepts square or bevel-cut joist ends - gives installers flexibility in how they prepare lumber, reducing unnecessary cuts and waste on the job site.
• Compatible with #9 x 2-1/2 in. Strong-Drive SD Connector screws or 0.162 in. x 3-1/2 in. nails - works with common fastener options so crews can use the tools and supplies already on hand.
• Made in the United States - produced to consistent quality standards with domestic manufacturing oversight, supporting reliable performance from hanger to hanger.

Why This Product

• Purpose-built for skewed right connections - rather than adapting a straight hanger with field modifications, this hanger is engineered specifically for 45 deg.-skewed right 4x6 framing, giving contractors a correctly fitting component right out of the box.
• Cleaner finished look without sacrificing strength - the concealed flange keeps metal hardware hidden on the header face, allowing structural framing to remain visually unobtrusive in settings where aesthetics are a factor alongside load requirements.
• Corrosion-resistant ZMAX coating suited for exterior use - the ZMAX finish is specifically intended for use with treated lumber and outdoor environments, making this hanger a dependable choice for deck framing and other moisture-exposed applications.
• Angle flexibility reduces installation headaches - the 40 deg. to 50 deg. accommodation range means this hanger can absorb minor layout variations without requiring a different part number, keeping projects on schedule and reducing material reorders.

Approved Applications

• Supporting 4x members framed at a 45 deg. skewed angle in wood construction
• Floor framing systems requiring angled joist connections
• Deck framing where a skewed right joist-to-beam connection is required

Installation

Fasten using #9 x 2-1/2" Strong-Drive SD Connector screws OR 0.162" x 3-1/2" nails. Fill all round and obround nail holes with specified fasteners to achieve published table loads. Where noted, triangle holes in the joist flange may be filled for additional uplift capacity. The joist end may be square cut or bevel cut. These hangers cannot be modified but will accommodate a 40 deg.- to 50 deg.-skewed joist.

Frequently Asked Questions

What lumber size does the HSURC46Z support?

The HSURC46Z is engineered to support 4x6 lumber members, with the hanger's heavy U-shaped design encapsulating the top flange of the joist for a secure connection.

Does this hanger only work at exactly 45 deg., or can it accommodate nearby angles?

While the HSURC46Z is designed as a 45 deg.-skewed right hanger, it accommodates joist skew angles ranging from 40 deg. to 50 deg., providing flexibility for installations that are not strictly at 45 deg..

Do I need web stiffeners when installing the HSURC46Z?

No, web stiffeners are not required under standard installation conditions. The heavy U-shaped hanger encapsulates the top flange of the joist, eliminating the need for them in typical applications.

What coating does the HSURC46Z have, and what gauge steel is it made from?

The HSURC46Z features a ZMAX coating for enhanced corrosion resistance and is constructed from 14-gauge steel, making it suitable for heavy-load applications.
