The Simpson 4x10 Concealed Flange Joist Hanger Skewed Right ZMAX HSURC410Z is a heavy-duty, 45 deg. right-skewed hanger engineered for structural wood framing applications where angled joist-to-header connections demand both precision and a clean visual result. Designed specifically to support 4x10 lumber members, this Simpson hanger combines a concealed flange profile with ZMAX coating and 14-gauge steel construction, making it a reliable choice for residential and light commercial projects where exposed framing conditions call for a more finished appearance without sacrificing load-carrying performance.

Key Features

• 45 deg. Right-Skewed Configuration - pre-engineered at a precise 45 deg. angle so contractors can execute angled framing connections accurately without field modification or guesswork.
• Concealed Header Flanges - flanges tuck behind the header face, keeping hardware out of sight in exposed framing and delivering cleaner sightlines in finished or visible installations.
• 14-Gauge Steel Construction - heavy-gauge steel provides the structural rigidity required for load-bearing floor and roof system applications involving 4x10 members.
• ZMAX Coating - an enhanced zinc coating provides corrosion resistance suited to treated-lumber environments and demanding job-site conditions.
• Square or Bevel Cut Joist End Compatibility - accepts both square-cut and bevel-cut joist ends, giving installers flexibility during layout and cutting without requiring additional hardware.
• No Web Stiffeners Required - standard installations proceed without additional reinforcement components, reducing material costs and simplifying the installation process.
• Made in the United States - domestic production supports consistent quality standards that professional contractors can count on across projects.

Why This Product

• Purpose-Built for Right-Skewed Connections - rather than adapting a straight hanger or relying on field modifications (which are not permitted with this product), the HSURC410Z is factory-engineered specifically for 45 deg. right-skewed 4x10 installations, ensuring structural integrity from the start.
• Aesthetics and Structural Performance Together - the concealed flange design addresses a real challenge in exposed framing: achieving a clean, professional appearance without stepping down in load capacity, making this hanger well suited to open-ceiling and visible-structure applications.
• ZMAX Protection for Treated Lumber Applications - the ZMAX coating is specifically recognized for use with preservative-treated and fire-retardant-treated lumber, broadening the range of code-compliant applications this hanger can serve.
• Streamlined Installation with Fewer Components - no web stiffeners are required for standard use, and the joist end can be square or bevel cut, reducing prep steps and keeping the installation process efficient on the job site.

Frequently Asked Questions

What size lumber member is the HSURC410Z designed to support?

The HSURC410Z is engineered specifically to support 4x10 lumber members. It is not a universal-fit hanger and should be matched to the correct member size for proper structural performance.

Can this hanger be used for installations where the skew angle is slightly different from 45 deg.?

Yes. While the HSURC410Z is designed as a 45 deg. right-skewed hanger and cannot be field-modified, it accommodates joist skews ranging from 40 deg. to 50 deg., providing a degree of flexibility for installations where the angle varies slightly from the nominal 45 deg..

What is the purpose of the concealed header flanges on this hanger?

The concealed header flanges are designed to deliver cleaner, more finished visible lines in exposed framing conditions. This makes the HSURC410Z well suited for architecturally finished spaces where the appearance of the framing connection is important.

What type of corrosion protection does the HSURC410Z have?

The HSURC410Z features a ZMAX coating, which is a heavy galvanized finish that provides enhanced corrosion resistance. This makes it suitable for demanding environments where standard coatings may not offer adequate protection.
