Product Description
The Simpson 3 x 4 Panelized Construction Hanger, ZMAX HF34NZ is a top-flange joist hanger engineered by Simpson exclusively for panelized roof construction. Modeled after the original hangers that defined Simpson's reputation, the HFN series brings a precision-oriented approach to panel fabrication - supporting the use of jigs and similar devices to deliver repeatable, efficient results across high-volume roofing assemblies.
Key Features
- Compression dimples instead of joist nails - locks the joist securely in place without additional fasteners at the joist, reducing labor steps and speeding up each installation
- Top-flange hanger design - supports precision fabrication workflows using jigs or similar devices, enabling consistent, repeatable panel assembly in controlled environments
- Drop-in panel compatibility - allows panels to drop easily into place, keeping the installation process moving quickly and reducing handling time on site
- ZMAX coating - provides enhanced corrosion resistance compared to standard galvanized finishes, helping protect the connection over the life of the structure
- Purpose-built for panelized roof construction - designed around the specific demands of this application, so every feature directly supports how the product is actually used
Why This Product
- Faster installation without sacrificing holding strength - by replacing joist nails with compression dimples, this hanger cuts fastening steps at the joist entirely, which translates directly to lower labor costs on repetitive panelized roof assemblies
- Built for precision fabrication environments - the top-flange design is specifically intended for use with jigs and similar devices, making it a natural fit for shops and crews that depend on consistent, controlled panel production
- Proven Simpson engineering - the HFN series traces its lineage to some of the earliest hangers Simpson produced, giving buyers confidence in a design with a long track record in the panelized construction industry
- Corrosion-resistant ZMAX finish - the ZMAX coating offers a meaningful upgrade over standard galvanized protection, supporting long-term connection performance in demanding roofing applications

Frequently Asked Questions
What type of construction is the HF34NZ designed for?
The HF34NZ is designed specifically for panelized roof construction only. It is intended for use in environments that utilize jigs or similar devices for precision fabrication, making it well-suited for controlled, repetitive panel assembly workflows.
What fasteners are required to install the HF34NZ?
The HF34NZ installs with 0.148 in. x 2-1/8 in. nails or 0.148 in. x 3 in. nails driven into the header. No joist nails are required, as compression dimples are used to lock the joist in place instead.
How do compression dimples improve installation on the HF34NZ?
Instead of relying on joist nails, the HF34NZ uses compression dimples to lock the joist securely in place. This design innovation speeds up the installation process, reducing labor time and contributing to a more cost-effective overall installation.
What does the ZMAX coating on the HF34NZ provide?
The ZMAX coating on the HF34NZ offers enhanced corrosion resistance compared to standard galvanized finishes. This helps protect the hanger against the elements and contributes to the long-term structural integrity of the panelized roof assembly.
