Product Description
The Simpson MIT3520 MIT Galvanized Top-Flange Joist Hanger for 2-5/16 in. x 20 in. Engineered Wood by Simpson Strong-Tie is engineered to support 90 deg. connections of I-joists to headers, delivering maximum down loads while requiring a minimum number of fasteners. Featuring a Funnel Flange design for easier member placement and positive-angle nailing (PAN) to minimize splitting, this top-flange hanger is a cost-effective, high-performance solution for engineered wood framing applications and is installed before the joist is in place.
Key Features

- 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
- Funnel Flange design allows for easier placement of members
- Made from 16-gauge steel
