The Simpson HIT422 Heavy Top-Flange I-Joist Hanger is engineered specifically for standard 90 deg. connections of I-joists to headers, delivering a structurally reliable and cost-effective alternative to welded hangers. Built from 16-gauge steel with a G90 zinc galvanized finish, this heavy top-flange hanger incorporates positive-angle nailing (PAN) - a design created specifically for I-joists to minimize splitting - along with extra triangle holes that support higher uplift loads, making it a dependable choice for engineered wood framing applications.

Key Features

• Positive-angle nailing (PAN) - drives nails at an angle specifically suited to I-joist construction, minimizing the risk of splitting during installation for a cleaner, safer connection
• Two face nails for uplift capacity - allows the hanger to handle higher uplift loads, adding an extra margin of structural strength to the connection
• Top-flange design for standard 90 deg. connections - provides a cost-effective, code-friendly solution for connecting I-joists to headers without the expense or complexity of welded hangers
• 16-gauge steel construction - delivers the heavy-duty strength required for large engineered lumber, giving builders confidence in load-bearing floor and roof framing
• G90 zinc galvanized coating - provides extra corrosion resistance, helping maintain structural integrity in moisture-prone environments over the long term

Why This Product

• Designed specifically for I-joists - the PAN nailing system and extra triangle holes are purpose-built features for engineered wood, reducing installation errors and splitting that can occur with general-purpose hangers
• Saves time on the job site - the time-saving PAN nailing system speeds up the nailing process, helping framers complete I-joist connections efficiently without sacrificing connection quality
• Strong uplift performance without welding - the combination of two face nails and extra triangle holes delivers higher uplift load capacity through a stamped steel hanger, eliminating the cost and lead time associated with welded alternatives
• Built to last with G90 galvanized protection - the zinc galvanized finish goes beyond basic corrosion resistance, making this hanger a sound long-term investment for projects where moisture exposure is a concern

Frequently Asked Questions

What type of connection is the HIT422 designed for?

The HIT422 is designed for standard 90 deg. connections of I-joists to headers, making it a reliable and cost-effective alternative to welded hangers in these applications.

What nails are required to install the HIT422?

Install the HIT422 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.

What does the G90 galvanized coating provide?

The G90 zinc galvanized coating provides extra corrosion resistance, helping the hanger maintain structural integrity in environments where moisture exposure is a concern.

How does the positive-angle nailing (PAN) feature benefit I-joist installations?

The positive-angle nailing (PAN) feature is specifically created for I-joists to minimize splitting during installation. Combined with two face nails, it also allows for higher uplift loads, enhancing the overall connection strength.
