The Simpson HIT420 Heavy Top-Flange I-Joist Hanger is built for standard 90 deg. connections of I-joists to headers, delivering a dependable and cost-effective alternative to welded hangers in engineered wood framing. Constructed from 16-gauge steel with a G90 zinc galvanized finish, this heavy top-flange hanger incorporates positive-angle nailing (PAN) technology specifically designed for I-joists to minimize splitting, while extra triangle holes work alongside two face nails to support higher uplift loads where demanding structural conditions require it.

Key Features

• Positive-angle nailing (PAN) - drives nails at the optimal angle for I-joists, reducing the risk of splitting and protecting the integrity of engineered wood members during installation
• Two face nails with extra triangle holes - work together to achieve higher uplift load capacity, giving builders confidence in connections that face greater structural demands
• Heavy top-flange design - transfers load through the flange for a secure, code-friendly connection without the cost or complexity of welded alternatives
• 16-gauge steel construction - provides the strength and rigidity required for heavy I-joist applications in residential and commercial framing
• G90 zinc galvanized finish - delivers enhanced corrosion resistance, making this hanger suitable for use in environments where moisture exposure is a concern
• Time-saving PAN nailing - speeds up installation compared to traditional nailing methods, reducing labor time on the job site

Why This Product

• Engineered specifically for I-joists - the PAN nailing feature is purpose-built to minimize splitting in engineered wood, a critical consideration that standard joist hangers do not address
• Higher uplift performance without welding - the combination of extra triangle holes and two face nails allows this hanger to handle elevated uplift loads while remaining a cost-effective alternative to welded connections
• Built for lasting performance - 16-gauge steel paired with a G90 zinc galvanized coating means this hanger resists corrosion and holds up over the life of the structure
• Straightforward 90 deg. installation - designed for standard right-angle header connections, this hanger simplifies layout and speeds up framing for contractors working with 3-1/2 in. x 20 in. engineered wood members

Frequently Asked Questions

What type of connection is the HIT420 designed for?

The HIT420 is designed for standard 90 deg. connections of I-joists to headers, making it a reliable and cost-effective solution for engineered wood framing applications.

What nails should be used to install the HIT420?

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.

What is positive-angle nailing (PAN) and why does it matter for I-joists?

Positive-angle nailing (PAN) is a nailing method specifically created for I-joists to minimize splitting during installation. The HIT420 is designed with this feature to protect the structural integrity of engineered wood members.

How does the HIT420 achieve higher uplift loads?

The HIT420 features extra triangle holes and two face nails, both of which work together to allow for higher uplift loads compared to standard joist hangers.
