The Simpson MIT5.12/16 Top-Flange Joist Hanger for 5 in. x 16 in. Engineered Wood is a precision-engineered metal connector from Simpson designed to support standard 90 deg. connections of I-joists to headers in engineered wood framing systems. Built from 16-gauge steel with a G90 zinc galvanized finish for enhanced corrosion resistance, this top-flange hanger is installed before the joist is in place and features a Funnel Flange design for easier member placement - making it a reliable, cost-effective alternative to welded hangers where high-load I-joist connections are required.

Key Features

• Positive-angle nailing (PAN) minimizes splitting of the flanges while permitting time-saving nailing from a better angle - reduces the risk of I-joist flange damage during installation while speeding up the nailing process on the job site.
• Nail hole material is not removed with positive-angle nailing - preserves the structural integrity of the connection point, maintaining the full strength of the fastened joint.
• Optional triangle nail holes for increased uplift capacity - gives contractors flexibility to upgrade the connection's resistance to uplift forces where project requirements demand it, when paired with properly-secured web stiffeners.
• Funnel Flange design for easier member placement - simplifies positioning of the I-joist before fastening, reducing installation time and improving accuracy in the field.
• Cost-effective solution for standard 90 deg. connections compared to welded hangers - delivers dependable load performance for engineered wood framing without the added expense of welded alternatives.
• Optional fastening with PAT for steel applications or steel headers - extends compatibility beyond wood headers, making this hanger adaptable to mixed-material framing conditions.
• 16-gauge steel construction with G90 zinc galvanized coating - provides a durable, corrosion-resistant connector suited for demanding structural environments.

Why This Product

• Engineered specifically for I-joist framing - the PAN feature and Funnel Flange design work together to address the unique installation and splitting challenges that come with engineered wood members, giving framers a connector purpose-built for the material rather than a general-purpose compromise.
• Versatile connection options for a range of project conditions - optional triangle nail holes for uplift capacity and optional PAT fastening for steel headers mean this single hanger model can adapt to varying structural demands and header materials without requiring a different product.
• A practical, cost-conscious alternative to welded hangers - delivers the high-load performance required for 90 deg. I-joist-to-header connections at a lower cost than welded connectors, helping contractors manage project budgets without sacrificing structural reliability.
• Installed before the joist is in place for a streamlined workflow - the top-flange design allows the hanger to be set on the header first, enabling a more efficient framing sequence and reducing the need for awkward repositioning once joists are being placed.

Frequently Asked Questions

What type of connection is the Simpson MIT5.12/16 designed to support?

The Simpson MIT5.12/16 is designed to support standard 90 deg. connections of I-joists to headers, making it well-suited for engineered wood framing applications where reliable, high-load connections are required.

What fasteners are required to install the MIT5.12/16?

Installation requires 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 1-1/2 in. nails in the joist. Optional fastening with PAT is also available for steel applications or steel headers.

What is the benefit of the positive-angle nailing (PAN) feature?

Positive-angle nailing (PAN) is specifically designed for I-joists to minimize splitting of the flanges while allowing nailing from a better angle to save time. Importantly, the nail hole material is not removed with PAN, preserving the integrity of the connection.

Can the MIT5.12/16 provide increased uplift capacity?

Yes. Optional triangle nail holes on the hanger may be used for increased uplift capacity. However, optional uplift nailing requires the addition of properly-secured web stiffeners to ensure a compliant and structurally sound installation.
