The Simpson MIU5.12/7 Face-Mount I-Joist Hanger is a heavy-duty face-mount connector engineered by Simpson for commercial, high-load, and double I-joist applications. Built to accommodate a 5 in. x 7 in. joist, this hanger is designed to perform without requiring web stiffeners in standard configurations, making it a reliable and efficient choice for demanding structural framing projects where load capacity and installation speed both matter.

Key Features

• Designed for commercial, high-load, and double I-joist applications - handles the structural demands of challenging framing projects without requiring web stiffeners in standard configurations, reducing material and labor complexity.
• Positive-Angle Nailing (PAN) - allows nails to be driven at a more natural, accessible angle, minimizing the risk of splitting joist flanges and helping crews work faster with fewer errors.
• Speed prongs - temporarily position and hold the connector in place during installation, freeing up a hand and keeping the hanger aligned before fastening for a smoother workflow.
• Optional triangle joist nail holes - when properly attached web stiffeners are used, these holes allow four additional 10dx1-1/2 in. joist nails to be added, enabling a total uplift load of 975 lbs. for higher-demand applications.
• Zinc Galvanized, G90 coating - provides corrosion resistance suited to the environments where structural connectors are typically installed, helping protect the connection over the long term.

Why This Product

• Versatile load performance with an upgrade path - the MIU5.12/7 performs in standard high-load and double I-joist configurations without web stiffeners, and can be upgraded to a 975 lb. total uplift capacity using the optional triangle nail holes with web stiffeners, giving builders flexibility across different project requirements.
• Installation features that save real time on the job - speed prongs and Positive-Angle Nailing work together to position the hanger quickly and allow faster, cleaner fastening, which adds up to meaningful time savings on multi-hanger framing projects.
• American-made construction from a trusted structural brand - the MIU5.12/7 is a Simpson product made in the United States, giving contractors and engineers confidence in sourcing and consistent manufacturing quality.
• Engineered to protect the joist during installation - PAN technology specifically reduces the risk of flange splitting as nails are driven, helping preserve the structural integrity of I-joists and avoiding costly field repairs or callbacks.

Frequently Asked Questions

Does the MIU5.12/7 require web stiffeners for standard installations?

In standard high-load and double I-joist applications, the MIU hanger is designed to function without requiring web stiffeners. However, properly attached web stiffeners are required when using the optional triangle joist nail holes for additional uplift capacity.

What is Positive-Angle Nailing (PAN) and why does it matter?

Positive-Angle Nailing (PAN) is a feature that allows nails to be driven at a better angle relative to the joist flange. This minimizes the risk of splitting the flanges during installation and saves time by enabling a more natural, accessible nailing position.

How can I achieve a total uplift load of 975 lbs. with the MIU5.12/7?

To achieve a total uplift load of 975 lbs., add four additional 10dx1-1/2 in. joist nails using the optional triangle joist nail holes. Properly attached web stiffeners are required when utilizing this configuration.

What fastener requirements apply to the MIU5.12/7?

All specified fasteners must be used as indicated for the application. It is also important to verify that the header can accommodate the required fasteners specified in the load table before installation.
