Product Description
The Simpson MIT314-2 MIT Galvanized Top-Flange Joist Hanger for Double 2-1/2 in. x 14 in. Engineered Wood from Simpson is built to deliver maximum down loads with a minimum number of fasteners when connecting I-joists to headers at 90 deg. Designed for installation before the joist is placed, this top-flange hanger incorporates a Funnel Flange design for easier member placement and positive-angle nailing (PAN) developed specifically for engineered wood I-joists - making it a practical, cost-effective alternative to welded hangers in engineered wood framing applications.
Key Features
- Positive-angle nailing (PAN) minimizes splitting of the flanges while permitting time-saving nailing from a better angle - protects the structural integrity of I-joist flanges and speeds up installation compared to conventional nailing methods.
- Nail hole material is not removed with positive-angle nailing - preserves the strength of the connection point, reducing the risk of weakening the joist flange during fastening.
- Optional triangle nail holes for increased uplift capacity - gives builders flexibility to boost performance in demanding load conditions; note that optional uplift nailing requires the addition of properly-secured web stiffeners.
- Optional fastening with PAT for steel applications and steel header connections - expands compatibility beyond wood headers, making this hanger adaptable to mixed-material framing assemblies.
- Funnel Flange design for easier member placement - reduces positioning effort during installation, improving workflow efficiency on the job site.
- Made from 16-gauge steel with a Zinc Galvanized G90 coating - delivers the structural rigidity engineered wood framing demands while providing extra corrosion resistance for long-term durability.
- Cost-effective solution for standard 90 deg. I-joist-to-header connections - provides reliable load transfer without the added expense or complexity of welded hangers.
Why This Product
- Purpose-built for engineered wood I-joists - the PAN design addresses the specific splitting risk associated with I-joist flanges, a challenge that generic joist hangers do not account for, making this hanger a more appropriate choice for engineered lumber framing.
- Installs before the joist is in place - the top-flange configuration combined with the Funnel Flange design lets framers set the hanger ahead of time, streamlining the sequence of work and reducing on-site handling.
- Flexible fastening options for wood and steel headers - with optional PAT fastening for steel applications and optional triangle nail holes for uplift capacity, this hanger adapts to a wider range of structural conditions without requiring a different product.
- G90 galvanized finish for lasting corrosion resistance - the Zinc Galvanized G90 coating helps protect the connector in environments where moisture exposure is a concern, supporting a longer service life in the structure.

Frequently Asked Questions
What type of connections is the Simpson MIT314-2 designed to support?
The MIT314-2 is designed to support 90 deg. connections of I-joists to headers, making it ideal for engineered wood framing applications that require maximum down loads with a minimum number of fasteners.
What is positive-angle nailing (PAN) and why is it important for I-joists?
Positive-angle nailing (PAN) is a design feature specifically created for I-joists to minimize splitting of the flanges. It also permits time-saving nailing from a better angle, and importantly, the nail hole material is not removed during the process, preserving the structural integrity of the connection.
What fasteners are required to install the MIT314-2?
The MIT314-2 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.
Can the MIT314-2 be used with steel headers, and is there any way to increase its uplift capacity?
Yes, the MIT314-2 features optional fastening with PAT for steel applications and steel header connections. Additionally, the optional triangle nail holes may be used for increased uplift capacity; however, optional uplift nailing requires the addition of properly-secured web stiffeners.
