Product Description
The Simpson MIT1.81/14 MIT Galvanized Top-Flange Joist Hanger is an engineered metal connector built to support 90 deg. connections of I-joists to headers in engineered wood framing applications. Designed to deliver maximum down-load capacity while requiring a minimum number of fasteners, this top-flange hanger from Simpson features a Funnel Flange design for easier member placement before the joist is set into position - making it a practical, cost-effective alternative to welded hangers on residential and commercial framing projects.
Key Features
- Positive-angle nailing (PAN) - minimizes splitting of I-joist flanges while allowing nailing from a better angle, so installation is faster and the structural integrity of each connection is preserved
- Nail hole material is retained with PAN - the nail hole material is not removed, maintaining the full strength of the connection at each fastening point
- Optional triangle nail holes for increased uplift capacity - gives builders a path to a stronger connection where uplift loads are a concern, with the addition of properly-secured web stiffeners
- Funnel Flange design - allows for easier placement of members before the joist is set, reducing layout time and simplifying installation on the jobsite
- Optional fastening with PAT for steel header applications - extends compatibility beyond wood headers so the hanger works in mixed-material framing assemblies
- 16-gauge steel construction - provides the structural rigidity needed to handle demanding down-load requirements in engineered wood framing systems
- Zinc Galvanized G90 finish - delivers extra corrosion resistance to help the connector hold up in moisture-exposed framing environments over the long term
Why This Product
- Engineered specifically for I-joists - the positive-angle nailing system and Funnel Flange design are purpose-built features for engineered wood applications, reducing the risk of flange splitting and making precise placement easier compared to generic hangers
- Fewer fasteners, no sacrifice in performance - the MIT1.81/14 is designed to achieve maximum down-load capacity with a minimum number of fasteners, which means less hardware and less installation time without compromising the strength of the connection
- Cost-effective alternative to welded hangers - delivers dependable 90 deg. I-joist-to-header connections at a lower cost than welded options, making it a practical choice for projects where budget and efficiency both matter
- Versatile fastening options - optional PAT fastening for steel header applications means the hanger adapts to different header materials, reducing the need to source separate connectors for mixed-construction framing assemblies

Frequently Asked Questions
What type of joist is the Simpson MIT1.81/14 designed to support?
The MIT1.81/14 is specifically designed to support 90 deg. connections of I-joists to headers, making it well-suited for engineered wood applications that require dependable down-load capacity with a minimum number of fasteners.
What is positive-angle nailing (PAN) and why does it matter?
Positive-angle nailing (PAN) is a feature specifically created for I-joists that minimizes splitting of the flanges while allowing nailing from a better angle to save time. Importantly, with PAN the nail hole material is not removed, preserving the integrity of the connection.
What fasteners are required to install the MIT1.81/14?
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 steel header applications, optional fastening with PAT is also available.
Can the MIT1.81/14 be used in applications requiring increased uplift capacity?
Yes. The hanger features 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 a code-compliant and structurally sound installation.
