Product Description
The Simpson MIT316 Top-Flange I-Joist Hanger from Simpson is an engineered metal connector built to support 90 deg. connections of I-joists to headers in engineered wood framing applications. Constructed from 16-gauge steel with a G90 zinc galvanized finish for corrosion resistance, this top-flange hanger features a Funnel Flange design for easier member placement and positive-angle nailing (PAN) technology specifically developed for I-joists - delivering maximum down loads while keeping fastener counts to a minimum.
Key Features
- Positive-angle nailing (PAN) with nail hole material retained - minimizes splitting of I-joist flanges while allowing faster, easier nailing from a more favorable angle, protecting structural integrity at the connection point
- Funnel Flange design - guides the joist into position before it is fully set, simplifying installation and reducing placement errors on the job site
- Optional triangle nail holes for uplift capacity - gives installers flexibility to increase uplift resistance where needed, when paired with properly secured web stiffeners
- Optional PAT fastening for steel header applications - expands compatibility beyond wood headers to steel applications, reducing the need for alternative connectors
- 16-gauge steel construction with G90 zinc galvanized finish - provides the corrosion resistance required for engineered wood framing environments while maintaining the strength needed for heavy down-load applications
- Cost-effective alternative to welded hangers - delivers reliable 90 deg. joist-to-header connections without the added expense of welded hardware, making it a practical choice for production framing
Why This Product
- Engineered specifically for I-joists - the PAN design and Funnel Flange work together to address the unique splitting and placement challenges of engineered wood members, making this hanger a purpose-built solution rather than a generic connector
- Handles maximum down loads with fewer fasteners - the MIT316 is designed to transfer high loads efficiently, reducing installation time and hardware costs without sacrificing connection performance
- Versatile enough for wood and steel headers - with optional PAT fastening for steel applications, this hanger adapts to a wider range of structural conditions, minimizing the need to source multiple connector types for a single project
- Built-in uplift flexibility for demanding applications - optional triangle nail holes allow contractors to dial in additional uplift capacity on the same hanger, providing a scalable solution when project requirements call for it

Frequently Asked Questions
What type of connection is the MIT316 designed to support?
The MIT316 is designed to support 90 deg. connections of I-joists to headers, making it well-suited for engineered wood framing applications where reliable right-angle joist-to-header connections are required.
What nails should be used to install the MIT316?
Install 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.
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 this method, preserving the structural integrity of the connection.
Can the MIT316 be used with steel headers?
Yes. The MIT316 features optional fastening with PAT for steel applications and steel header connections, providing additional versatility beyond standard wood header installations.
