The Simpson H10A-2Z Hurricane Tie is a U-shaped, double-sided rafter and truss connector built for high-uplift roof-to-wall applications where single-sided ties fall short. Engineered by Simpson to hold the rafter or truss on both sides simultaneously, it forms part of a continuous load path to resist wind and seismic forces - making it a reliable choice for demanding structural connections in both new construction and retrofit work. Embossments add stiffness in crucial areas for improved performance, while slots allow field bending up to a maximum pitch of 6:12 to accommodate angled blocking. The ZMAX galvanized finish delivers extra corrosion resistance for exterior and treated-wood applications, and optional fastener holes let you connect roof blocking directly to the top plate without additional hardware.

Key Features

• U-shaped double-sided design - holds the rafter or truss on both sides for higher uplift resistance, eliminating the need for two separate single-sided ties and speeding up installation
• Holds a double-ply member - the H10A-2 model is specifically designed for double-ply framing members, giving builders a single connector solution for built-up beams and rafters
• Forms part of a continuous load path - engineered to resist wind and seismic forces, supporting code-compliant roof-to-wall connections in high-uplift zones
• ZMAX galvanized finish - offers extra corrosion resistance beyond standard galvanization, making this tie well-suited for exterior environments and pressure-treated lumber applications
• Embossments for added stiffness - strategically placed embossments reinforce the connector in crucial areas, improving structural performance under load
• Slots for field bending up to 6:12 pitch - allows on-site adjustment to accommodate angled blocking without special tools or custom orders
• Approved for use with the Strong-Drive SD Connector screw - gives installers a pre-approved fastener option for consistent, code-supported connections
• Made from 18-gauge steel - provides a strong yet workable connector profile suited to standard framing applications

Why This Product

• Faster installation in high-uplift applications - because the H10A-2Z wraps around both sides of the rafter or truss, it replaces what would otherwise require two single-sided ties, cutting labor time at the roof-to-wall connection
• Built for treated-wood and exterior conditions - the ZMAX coating is specifically formulated to resist corrosion in the demanding environments where pressure-treated lumber is used, helping the connector hold up over the long term
• Field-adjustable for real-world framing - the slot design allows bending on site to match angled blocking up to a 6:12 pitch, reducing the need for pre-planned custom fabrication and keeping projects moving
• Engineered for structural load path continuity - with optional fastener holes for roof blocking-to-top-plate connections and a design that resists both wind and seismic forces, this tie supports a complete, code-conscious approach to roof framing

Frequently Asked Questions

What makes the H10A-2Z different from a standard single-sided hurricane tie?

The H10A-2Z is a U-shaped tie that holds the rafter or truss on both sides simultaneously, providing higher uplift resistance than a standard single-sided tie. This design also offers faster installation compared to using two separate single-sided ties, and its embossments add stiffness in crucial areas for improved overall performance.

Is the H10A-2Z suitable for use with pressure-treated lumber or exterior applications?

Yes. The H10A-2Z features a ZMAX galvanized finish, which is specifically formulated to offer extra corrosion resistance for exterior and treated-wood applications, making it appropriate for environments where standard galvanization may not provide sufficient protection.

Can the H10A-2Z be installed with screws instead of nails?

Yes. The H10A-2Z is approved for installation with the Strong-Drive SD Connector screw in addition to standard nails. Always use all specified fasteners and follow installation guidelines to ensure proper performance.

Can this hurricane tie accommodate pitched or angled roof blocking?

Yes. The H10A-2Z includes slots that allow field bending up to a maximum pitch of 6:12, making it adaptable to angled blocking installations. Note that hurricane ties do not replace solid blocking, and when installing on plated trusses on the side opposite the truss plate, fasteners should not be driven through the truss plate from behind, as this can compromise truss performance.
