Product Description
The Simpson MIT3514-2 MIT Galvanized Top-Flange Joist Hanger for Double 2-5/16 in. x 14 in. Engineered Wood by Simpson is purpose-built to deliver maximum downward load capacity for standard 90 deg. connections of I-joists to headers, all while keeping fastener counts to a minimum. Constructed from 16-gauge steel with a G90 zinc galvanized finish, this top-flange hanger is designed for installation before the joist is placed, making it a practical choice for engineered wood framing projects where precision, durability, and installation efficiency matter.
Key Features
- Positive-angle nailing (PAN) - minimizes splitting of the I-joist flanges and allows nailing from a more accessible angle, saving time without removing nail hole material for a cleaner, stronger connection.
- Funnel Flange design - guides members into position more easily during installation, reducing handling difficulty and helping framers work faster and with greater accuracy.
- Optional triangle nail holes - provide a path to increased uplift capacity when project loads demand it; note that optional uplift nailing requires the addition of properly-secured web stiffeners.
- Top-flange installation before joist placement - streamlines the framing sequence by allowing the hanger to be set on the header first, eliminating the need to maneuver fasteners in tight spaces after the joist is in position.
- Optional PAT fastening compatibility - supports steel header applications, giving this hanger flexibility across a wider range of structural framing scenarios.
- 16-gauge steel construction with G90 galvanized coating - delivers corrosion resistance suited to demanding job site environments, helping the hanger maintain structural integrity over the long term.
- Cost-effective alternative to welded hangers - provides a reliable solution for standard 90 deg. I-joist-to-header connections without the added expense or lead time associated with custom welded connectors.
Why This Product
- Engineered for I-joist framing - the PAN design and Funnel Flange are specifically developed for engineered wood members, addressing the unique splitting and placement challenges that standard hangers are not built to handle.
- Maximum load with fewer fasteners - the MIT series is designed to achieve high downward load ratings while requiring a minimum number of fasteners, reducing material use and installation labor without compromising structural performance.
- Built-in versatility for varied structural demands - optional triangle nail holes for uplift capacity and optional PAT fastening for steel headers mean this single hanger can adapt to a range of connection requirements on the same job.
- Durable G90 galvanized finish for lasting performance - the zinc galvanized coating provides extra corrosion resistance, making this connector a dependable choice for framing applications where long-term integrity is a priority.

Frequently Asked Questions
What type of connection does the Simpson MIT3514-2 support?
The MIT3514-2 is designed to support standard 90 deg. connections of I-joists to headers, making it suitable for engineered wood framing applications where precise perpendicular joist-to-header connections are required.
What fasteners are required to install the MIT3514-2?
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. The positive-angle nailing (PAN) design allows for easier nailing from a better angle without removing nail hole material.
What is the benefit of the Funnel Flange design on this hanger?
The Funnel Flange design allows for easier placement of members during installation. Because it is a top-flange hanger, it is installed before the joist is set in place, streamlining the framing process.
Can the MIT3514-2 be used for applications requiring increased uplift capacity?
Yes. Optional triangle nail holes are available on the MIT3514-2 and may be used for increased uplift capacity. However, optional uplift nailing requires the addition of properly-secured web stiffeners to ensure structural integrity.
