The Simpson PF24B PFB Galvanized Post-Frame Hanger is a top-flange joist hanger from Simpson engineered specifically for post-frame construction. Dome-shaped joist nail holes guide nails into the proper installation angle automatically, eliminating guesswork and ensuring consistently correct fastening on every connection. A folded seat raises the 2x4 joist slightly above the seat radius to enable a tighter connection to the back of the hanger, delivering a secure, precision fit where it matters most in post-frame building.

Key Features

• Solid one-piece top flange - allows for accurate and fast installation, reducing setup time and minimizing alignment errors on the job.
• Installation prongs - make setting the hanger quick and easy, so crews can position and hold the hanger in place without extra hands or tools.
• Double-shear nailing design - distributes the load throughout two points on each joist, providing greater strength with fewer nails and a more efficient fastening schedule.
• Dome-shaped joist nail holes - guide nails into the proper installation angle automatically, ensuring consistent results without extra measuring or adjustment during installation.
• Folded seat - raises the 2x4 joist slightly above the seat radius to enable a tighter connection to the back of the hanger, improving fit and overall structural integrity.
• 20-gauge steel construction - provides reliable structural performance suited to the demands of post-frame applications.
• Zinc Galvanized G90 finish - delivers corrosion resistance appropriate for the demanding conditions commonly encountered in post-frame construction environments.

Why This Product

• Built-in nail guidance for faster, more consistent installs - the dome-shaped joist nail holes angle each nail correctly without extra measuring, helping crews work faster and reducing the risk of improper fastening on purlin and joist connections.
• Stronger connection with fewer fasteners - the double-shear nailing design spreads the load across two points on each joist, so you get superior holding strength without overdriving nails or using more hardware than necessary.
• Designed specifically for post-frame construction - every feature of this hanger, from the one-piece top flange to the folded seat, is purpose-built for 2x4 joist and purlin connections to headers in post-frame buildings, making it a natural fit for agricultural, commercial, and utility post-frame projects.
• G90 galvanized protection built to last - the Zinc Galvanized G90 coating guards against corrosion in the tough, moisture-prone environments typical of post-frame construction, helping the connection maintain its integrity over the life of the structure.

Frequently Asked Questions

What fasteners are required to install the PF24B?

The PF24B can be installed using one of two fastener configurations: (2) 0.148 in. x 3 in. nails in the top and (2) 0.148 in. x 3 in. nails in the joist, OR (2) 0.148 in. x 1-1/2 in. nails in the top, (2) 0.148 in. x 1-1/2 in. nails in the face, and (2) 0.148 in. x 1-1/2 in. nails in the joist.

What is the purpose of the dome-shaped joist nail holes?

The dome-shaped joist nail holes are designed to guide nails into the proper installation angle automatically, ensuring consistent and correctly angled fastening without extra measuring or adjustment during installation.

Why does the PF24B feature a folded seat?

The folded seat raises the 2x joist slightly above the seat radius to enable a tighter connection to the back of the hanger, resulting in a more secure and precise fit in post-frame construction applications.

What corrosion protection does the PF24B hanger have?

The PF24B is coated with a Zinc Galvanized G90 finish, which provides reliable corrosion resistance suitable for the demanding conditions commonly found in post-frame construction environments.
