The Simpson HU46Z Heavy-Duty Face-Mount Joist Hanger is engineered by Simpson to deliver the additional strength and safety factors demanded by load-bearing framing connections. Built from 14-gauge steel with a ZMAX galvanized finish, this face-mount hanger is purpose-built for nominal 4x6 lumber and is the go-to choice of engineers and contractors on projects where tested, code-compliant performance is non-negotiable.

Key Features

• Extra optional triangle holes for additional load - gives installers flexibility to increase connection capacity when project conditions call for greater load transfer.
• Tested, load-rated, and code-compliant HU-series design - meets building code requirements for both residential and commercial framing, removing guesswork from structural sign-off.
• 14-gauge steel construction - provides the heavy-duty rigidity needed for applications where a standard-gauge hanger would not deliver adequate safety factors.
• ZMAX galvanized coating - offers extra corrosion resistance beyond standard galvanized finishes, making this joist hanger well-suited for demanding or moisture-exposed environments.
• 3-9/16 in. seat width sized for nominal 4x6 lumber - ensures a precise, stable fit that keeps the joist properly seated and aligned throughout the life of the structure.

Why This Product

• Heavy-duty performance where it counts - the HU-series is specifically designed for structures requiring additional strength and safety factors, making it a reliable upgrade over standard-duty hangers in critical framing connections.
• Built-in code compliance - because these hangers are independently tested and load-rated, they support a smoother inspection process on projects that must meet building codes.
• Superior corrosion protection - the ZMAX galvanized finish provides enhanced durability compared to standard galvanized coatings, helping protect the connection over the long term in challenging conditions.
• Engineered flexibility through optional triangle holes - the ability to add fasteners in the extra triangle holes means contractors can adapt the connector to higher-load situations without switching to a different product.
