The Simpson HHUS46Z HHUS ZMAX Galvanized Face-Mount Joist Hanger for 4x6 is a heavy-capacity face-mount hanger from Simpson engineered for applications where higher load values are required. Built to provide reliable support underneath the joist, rafter, or beam, it delivers a strong, secure connection for 4x6 nominal lumber. Its ZMAX galvanized coating makes it a dependable choice for exterior framing and treated-wood construction where long-term corrosion resistance is a priority.

Key Features

• Double-shear nailing design - distributes the load through two points on each joist nail, increasing strength and load-carrying capacity at every connection point so your structural joint performs at a higher level.
• Fewer nails required with standard nail compatibility - the double-shear geometry allows you to achieve a high-performance connection using standard nails, reducing material handling and speeding up installation on the job site.
• ZMAX galvanized coating - provides extra corrosion resistance beyond standard galvanized finishes, making this hanger well-suited for exterior applications and direct contact with pressure-treated lumber where moisture and chemical exposure are concerns.
• 14-gauge steel construction - delivers the heavy-duty structural capacity expected from the HHUS hanger line, which is specifically designed for connections where higher load values are needed compared to standard joist hangers.
• Designed for 4x6 nominal lumber - engineered to fit a 4x6 joist, rafter, or beam precisely, ensuring proper load transfer and a secure face-mount connection without field modification.
• Installs with 16d common nails - uses widely available fasteners, keeping your fastener inventory simple and procurement straightforward on any framing project.

Why This Product

• Built for demanding load requirements - the HHUS hanger line is engineered specifically for applications where higher load values are needed, making this an appropriate choice for structural connections that standard hangers may not be rated to handle.
• Corrosion resistance where it counts most - ZMAX galvanization offers extra protection against moisture and the chemicals present in treated lumber, helping maintain connection integrity in exterior decks, pergolas, and other exposed framing over time.
• Faster, simpler installation - the double-shear nailing system allows for fewer nails and the use of standard 16d common nails throughout, cutting down on installation time and reducing the number of specialty fasteners you need on site.
• American-made quality from a trusted structural brand - produced by Simpson, a widely recognized name in structural connectors, this hanger brings consistent manufacturing quality to a critical load-bearing connection in your framing system.

Frequently Asked Questions

What is double-shear nailing and why does it matter?

Double-shear nailing distributes the load through two points on each joist nail rather than one, resulting in greater strength and load-carrying capacity at each connection point. This allows for fewer nails overall while still achieving a high-performance connection.

What type of nails should be used to install the HHUS46Z?

The HHUS46Z should be installed with 16d common nails. The double-shear design also allows for the use of standard nails for all connections, simplifying installation.

Why is ZMAX galvanization important for this joist hanger?

ZMAX galvanization provides extra corrosion resistance compared to standard galvanized coatings, making the HHUS46Z suitable for exterior applications and use with treated lumber, where standard coatings may degrade more quickly due to moisture or chemical exposure.

What lumber size is the HHUS46Z designed to support?

The HHUS46Z is designed for a nominal 4x6 joist, rafter, or beam. It is part of the HHUS hanger line, which is specifically engineered for applications requiring higher load values than standard joist hangers provide.
