Product Description
The Simpson Strong-Tie MIT320 MIT Galvanized Top-Flange Joist Hanger for 2-1/2 in. x 20 in. Engineered Wood is engineered by Simpson Strong-Tie to support 90 deg. connections of I-joists to headers with maximum down load capacity using a minimum number of fasteners. Featuring a Funnel Flange design for easier member placement and positive-angle nailing (PAN) to minimize flange splitting, this top-flange hanger is installed before the joist is in place, making it a cost-effective and efficient solution for engineered wood framing applications.
Key Features
- Positive-angle nailing (PAN) minimizes splitting of the flanges while permitting time-saving nailing from a better angle
- With positive-angle nailing, the nail hole material is not removed
- Optional triangle nail holes may be used for increased uplift capacity; optional uplift nailing requires the addition of properly-secured web stiffeners
- Cost-effective solution for standard 90 deg. connections in comparison to welded hangers
- Features optional fastening with PAT for steel applications/header
- Actual joist size: 2-1/2 in. x 20 in.
- Made from 16-gauge steel
- Galvanized (G90) for extra corrosion resistance

Frequently Asked Questions
- What is the purpose of the Funnel Flange design on the MIT320?
- The Funnel Flange design on the MIT320 allows for easier placement of members during installation. Because this top-flange hanger is installed before the joist is in place, the Funnel Flange helps guide the I-joist into position more efficiently, saving time on the job site.
- What type of nailing system does the MIT320 use, and why does it matter for I-joists?
- The MIT320 features positive-angle nailing (PAN), which is specifically created for I-joists to minimize splitting of the flanges. With PAN, the nail hole material is not removed, which helps maintain the structural integrity of the flange while also allowing nailing from a better angle for time savings during installation.
- Can the MIT320 be used for applications requiring increased uplift capacity?
- Yes. The MIT320 includes 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.
- What corrosion protection does the MIT320 provide, and what fasteners are required for installation?
- The MIT320 is coated with a G90 zinc galvanized finish for extra corrosion resistance. For installation, use 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.
