The Simpson MIT416 Top-Flange Joist Hanger for 3-1/2 in. x 16 in. Engineered Wood from Simpson is engineered to support 90 deg. connections of I-joists to headers, delivering maximum down loads while requiring a minimum number of fasteners. Designed for installation before the joist is in place, this top-flange hanger features a Funnel Flange design for easier member placement and positive-angle nailing technology developed specifically for I-joist applications - making it a practical, cost-effective alternative to welded hangers in standard engineered wood framing.

Key Features

• Positive-angle nailing minimizes flange splitting - PAN technology lets installers drive nails from a better angle, reducing the risk of splitting I-joist flanges and speeding up the nailing process on the job site.
• Nail hole material is not removed with PAN - preserving the structural integrity of the connection point for a more dependable hold compared to punched-out hole designs.
• Optional triangle nail holes for increased uplift capacity - gives builders flexibility to upgrade the connection for higher-demand applications when web stiffeners are properly secured.
• Compatible with steel headers via optional PAT fastening - expands the range of framing applications beyond wood headers without requiring a different hanger model.
• Funnel Flange design for easier member placement - guides the I-joist into position during installation, reducing fumbling and improving placement accuracy before fastening.
• Made from 16-gauge steel with G90 zinc galvanized coating - provides the structural strength and corrosion resistance needed for demanding framing environments.
• Cost-effective solution for standard 90 deg. connections - delivers reliable structural performance comparable to welded hangers at a lower cost for typical engineered wood framing projects.

Why This Product

• Built for engineered wood framing - the MIT416 is purpose-designed for I-joist-to-header connections, with PAN technology and a Funnel Flange that address the specific challenges of working with engineered lumber, making it a more fitting choice than general-purpose hangers for these applications.
• Fewer fasteners, maximum load performance - the top-flange design is optimized to achieve maximum down loads with a minimum number of fasteners, reducing installation time while maintaining the structural performance engineers specify.
• Flexible enough for uplift and steel header applications - optional triangle nail holes support increased uplift capacity, and optional PAT fastening accommodates steel header connections, giving one hanger model the adaptability to handle a broader range of project conditions.
• Corrosion-resistant construction for long-term reliability - the G90 zinc galvanized finish provides an extra layer of protection against corrosion, helping the connector maintain structural integrity in the conditions typical of wood-framed construction.

Frequently Asked Questions

What type of connection is the MIT416 designed to support?

The MIT416 is designed to support 90 deg. connections of I-joists to headers, making it a cost-effective solution for standard structural connections in engineered wood framing applications.

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

Positive-angle nailing (PAN) is a design feature specifically created for I-joists that minimizes splitting of the flanges while permitting time-saving nailing from a better angle. Importantly, the nail hole material is not removed with PAN, preserving the structural integrity of the connection.

What fasteners are required to install the MIT416?

The MIT416 should be installed with 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 for a proper and code-compliant installation.

Can the MIT416 be used in applications requiring increased uplift capacity?

Yes. The MIT416 features optional triangle nail holes that may be used for increased uplift capacity. However, optional uplift nailing requires the addition of properly-secured web stiffeners to ensure structural performance.
