The Simpson HU612Z ZMAX Galvanized Face-Mount Joist Hanger is a heavy-duty structural connector built by Simpson Strong-Tie for 6x12 lumber in applications where strength, durability, and code compliance are non-negotiable. Formed from 14-gauge steel with ZMAX galvanization, this face-mount hanger delivers reliable performance in exterior framing, deck construction, and treated-wood assemblies where standard connectors may fall short. Engineered and tested to meet code requirements, it carries the trusted performance standards that make Simpson Strong-Tie connectors the preferred choice of engineers and contractors on demanding structural projects.

Key Features

• 14-gauge steel construction - delivers the heavy-duty strength needed for structures requiring additional load capacity and safety factors
• ZMAX galvanization - provides extra corrosion resistance for exterior and treated-wood applications, extending the service life of the connection in harsh environments
• "U" design - allows for flexibility of placement on the header, making installation more forgiving and adaptable on the job site
• Extra optional triangle holes - give installers the ability to add fasteners for increased load capacity when project conditions demand it
• Tested, load rated, and code compliant - HU-series hangers meet the documentation requirements contractors and inspectors need for permitted structural work
• Nominal joist size 6x12 with a 5-1/2 in. seat width - sized precisely to cradle the supported member securely and maintain proper joist alignment

Why This Product

• Built for demanding connections - the HU612Z is specifically engineered for structures requiring additional strength and safety factors, making it the right choice for heavy timber framing and load-critical assemblies rather than a standard-duty substitute
• Corrosion resistance where it counts most - ZMAX galvanization goes beyond standard coatings to protect against the accelerated corrosion that treated lumber and exterior exposure can cause, helping maintain connection integrity over time
• Flexibility without sacrificing performance - the "U" design combined with optional triangle holes means installers can adapt placement and load strategy to real-world site conditions while staying within tested, code-compliant parameters
• Backed by proven engineering - as a Simpson Strong-Tie product, the HU612Z is manufactured to rigorous quality standards and carries load ratings that support engineer specifications and building code submissions

Frequently Asked Questions

What size joist is the HU612Z designed to support?

The HU612Z is designed for a nominal joist size of 6x12, with a seat width of 5-1/2 in. to securely cradle the supported member.

What fasteners are required to install the HU612Z?

Install with (16-22) 0.162 in. x 3-1/2 in. nails in the header and (6-8) 0.162 in. x 3-1/2 in. nails in the joist for a proper, code-compliant connection.

Why does the HU612Z use ZMAX galvanization?

ZMAX galvanization offers extra corrosion resistance, making the HU612Z well suited for exterior and treated-wood applications where standard galvanization may not provide sufficient protection.

Is the HU612Z tested and code compliant?

Yes. HU-series hangers are tested, load rated, and code compliant, and the "U" design allows for flexibility of placement on the header, providing reliable performance in structures requiring additional strength and safety factors.
