The Simpson MIU5.12/16 MIU Galvanized Face-Mount I-Joist Hanger is a heavy-duty structural connector from Simpson engineered for commercial and high-load I-joist applications. Built to support a 5 in. x 16 in. engineered wood member, this face-mount hanger eliminates the need for web stiffeners, streamlining the connection process on demanding framing projects. Positive-angle nailing and a robust 16-gauge galvanized construction make this hanger a dependable solution for contractors working with large engineered lumber in load-critical assemblies.

Key Features

• Positive-angle nailing (PAN) - allows nails to be driven at a more effective angle into the joist flange, minimizing splitting and reducing installation time on the job site
• No web stiffeners required - simplifies installation in commercial and high-load I-joist applications, saving labor and material costs
• 16-gauge steel construction - delivers the structural rigidity and load capacity needed for heavy engineered wood framing connections
• Zinc galvanized G90 finish - provides enhanced corrosion resistance, supporting long-term performance in moisture-exposed framing environments
• Non-modifiable design - ensures the hanger maintains its engineered load ratings and structural integrity as manufactured, supporting code-compliant installations

Why This Product

• Engineered for high-load I-joist applications - the MIU5.12/16 is purpose-built for commercial framing where large engineered wood members require a reliable, high-capacity face-mount connection without added hardware like web stiffeners
• Faster, safer nailing with PAN technology - positive-angle nailing lets installers drive fasteners from a better angle, reducing flange splitting and keeping the installation process efficient without sacrificing connection strength
• Corrosion-resistant finish for lasting durability - the G90 galvanized coating offers a higher level of protection against corrosion compared to standard finishes, making this hanger well-suited for structural environments where long-term integrity matters
• Manufactured in the United States by a trusted structural connector brand - Simpson is a recognized name in structural hardware, and the MIU5.12/16 is built domestically to consistent quality standards that contractors rely on for load-bearing framing work

Frequently Asked Questions

What size joist is the MIU5.12/16 designed to support?

The MIU5.12/16 is designed for an actual joist size of 5 in. x 16 in., making it suitable for large engineered wood members used in commercial and high-load I-joist applications.

What fasteners are required to install this hanger?

Installation requires 0.162 in. x 3-1/2 in. nails and 0.148 in. x 1-1/2 in. nails. Always use all specified fasteners to ensure a proper and code-compliant connection.

What is positive-angle nailing (PAN) and why does it matter?

Positive-angle nailing (PAN) is a design feature of the MIU series that allows nails to be driven at an improved angle into the joist flange. This minimizes splitting of the flanges and enables faster, more efficient nailing during installation.

Can the MIU5.12/16 hanger be field-modified to fit different applications?

No. These hangers cannot be modified. The MIU5.12/16 is engineered specifically for its listed member size and must be used as manufactured to maintain its structural integrity and load ratings.
