Product Description
The Simpson MIT3514 Top-Flange Joist Hanger for 2-5/16 in. x 14 in. Engineered Wood from Simpson Strong-Tie is purpose-built 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 that simplifies member placement and speeds up the framing process. Built from 16-gauge steel with a G90 zinc galvanized finish, it provides the corrosion resistance and structural reliability that engineered wood framing demands.
Key Features
- Positive-angle nailing (PAN) minimizes splitting of the flanges while permitting time-saving nailing from a better angle - lets installers work faster without risking damage to the I-joist flanges, reducing callbacks and rework on the job site.
- Nail hole material is not removed with positive-angle nailing - preserves the structural integrity of each nail hole, maintaining full load capacity at every fastening point.
- Optional triangle nail holes for increased uplift capacity - gives engineers and builders flexibility to upgrade the connection's uplift resistance where conditions demand it, though properly secured web stiffeners are required when this option is used.
- Funnel Flange design for easier member placement - guides the I-joist into position smoothly, cutting placement time and reducing frustration during installation.
- Cost-effective alternative to welded hangers for standard 90 deg. connections - delivers a code-ready, engineered connection without the added expense or lead time associated with custom welded hardware.
- Optional fastening with PAT for steel applications and steel header connections - extends the hanger's versatility to steel-framed assemblies, giving contractors a single connector solution across mixed-material conditions.
- Made from 16-gauge steel with G90 zinc galvanized coating - provides extra corrosion resistance, making this I-joist hanger appropriate for framing environments where moisture exposure is a concern.
Why This Product
- Engineered specifically for I-joist framing - the MIT3514 is designed around the actual dimensions and splitting sensitivities of engineered wood I-joists, so the positive-angle nailing geometry actively protects the material you are fastening rather than working against it.
- Faster installation without sacrificing connection strength - the Funnel Flange design and positive-angle nail holes allow crews to set and fasten joists more quickly, while still achieving the maximum down load capacity the connection requires with a minimum number of fasteners.
- Built-in flexibility for demanding load conditions - optional triangle nail holes let the same hanger be upgraded for higher uplift capacity, and optional PAT fastening opens the connector to steel header applications, reducing the number of SKUs a framer needs to carry on site.
- Durable, corrosion-resistant construction from a trusted manufacturer - 16-gauge steel and a G90 zinc galvanized finish mean this top-flange I-joist connector is built to hold up over the life of the structure, with domestic manufacturing and a finish specification that meets common code requirements for corrosion protection.

Frequently Asked Questions
What type of joist connection is the MIT3514 designed for?
The MIT3514 is designed to support 90 deg. connections of I-joists to headers, making it specifically suited for engineered wood applications where a reliable right-angle connection is required.
What size joist does the MIT3514 accommodate?
The MIT3514 is sized for an actual joist dimension of 2-5/16 in. x 14 in., matching standard engineered wood I-joist member sizes used in residential and commercial framing.
What nails are required to install the MIT3514?
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 for proper fastening per the manufacturer's requirements.
Does the MIT3514 offer any protection against corrosion?
Yes. The MIT3514 is coated with a G90 zinc galvanized finish, which provides extra corrosion resistance, making it suitable for use in environments where moisture exposure is a concern.
