The Simpson HSUL ZMAX Galvanized Joist Hanger for 4x10, Skewed Left is a 14-gauge steel connector engineered by Simpson Strong-Tie to deliver a reliable 45 deg. connection between a joist and a header in left-skewed framing applications. Built to support the joist from underneath, this hanger is well suited for angled deck framing, timber construction, and other structural wood projects where a left-hand skew is required. The ZMAX galvanized finish provides extra corrosion resistance, making it a dependable choice for exterior builds and assemblies involving treated lumber.

Key Features

• HSUL skewed-left configuration - purpose-built for left-hand skewed connections, eliminating the guesswork of field-modifying a standard hanger and ensuring a code-consistent result.
• Accommodates joists skewed 40 to 50 deg. - the built-in tolerance range handles minor framing variations without requiring a custom or special-order connector.
• Angled nail slots direct nails for proper installation - nails are guided into the correct position automatically, reducing installer error and helping meet load-rated performance requirements.
• Square cut or bevel cut joist end accepted - gives framers flexibility in how they prepare the joist, saving time on the job site.
• 14-gauge steel construction - heavy-duty thickness provides the structural strength needed to carry a nominal 4x10 member under real-world load conditions.
• ZMAX galvanization for extra corrosion resistance - outperforms standard galvanized finishes in outdoor environments and is compatible with treated-wood applications where standard coatings can break down over time.

Why This Product

• Precision-engineered for the 45 deg. skewed connection - rather than bending or adapting a standard hanger on site, this connector is factory-formed specifically for the left-skewed 4x10 application, resulting in a stronger, more consistent joint.
• ZMAX coating goes beyond basic galvanization - for exterior decks, covered porches, and structures built with pressure-treated lumber, the enhanced corrosion resistance of ZMAX helps the connector hold up in conditions that would degrade a standard finish over time.
• Designed by Simpson Strong-Tie for broad application versatility - the 40 to 50 deg. skew range and acceptance of both square-cut and bevel-cut joist ends mean this hanger adapts to realistic framing conditions rather than demanding perfect geometry.
• Straightforward installation guided by the hanger itself - angled nail slots that direct 16d common nails into the correct position reduce the chance of mis-driven fasteners, helping installers work efficiently while maintaining structural integrity.

Frequently Asked Questions

What angle does the HSUL410Z connect a joist to a header?

The HSUL410Z provides a 45 deg. connection between a joist and a header, and can accommodate joists skewed anywhere from 40 to 50 degrees.

What does "HSUL" mean, and how does it differ from HSUR?

HSUL indicates a skewed-left hanger, while HSUR indicates a skewed-right hanger. The two hangers are otherwise identical in design and function, differing only in the direction of the skew.

What type of nails should be used to install the HSUL410Z?

This hanger should be installed with 16d common nails. The angled nail slots built into the hanger help direct nails for proper installation.

Why choose ZMAX galvanization for this joist hanger?

ZMAX galvanization provides extra corrosion resistance compared to standard finishes, making the HSUL410Z suitable for exterior applications and use with treated wood where greater protection against the elements is required.
