The Simpson H1AZ H1A 18-Gauge ZMAX Galvanized Hurricane Tie from Simpson is engineered to positively connect trusses and rafters to the top plate of a wall, helping structures resist high winds and seismic forces. This U-shaped rafter tie is designed for nominal 2x lumber, and its double-sided design wraps both sides of the framing member simultaneously for stronger, faster connections than single-sided alternatives. Embossments at critical areas add stiffness where it matters most, while the ZMAX galvanized finish provides enhanced corrosion resistance for exterior and treated-wood applications.

Key Features

• Holds the rafter or truss on both sides - delivers high lateral load resistance from a single connector, strengthening the roof-to-wall connection against wind uplift and seismic forces
• Can be installed on inside or outside of wall, or both sides - gives framers flexibility to work with the structural layout that best suits the build
• Flanges can face either inward or outward - accommodates a wider range of framing configurations without requiring a separate left- or right-handed connector
• U-shaped design provides faster installation than using two single-sided ties - saves labor time by making a full double-sided connection in a single step
• Made from 18-gauge steel - provides a solid structural foundation suited for high-wind construction, general framing, and rafter applications
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - stands up to the harsh conditions and chemically treated lumber where standard galvanized finishes may fall short

Why This Product

• One connector does the work of two - the U-shaped profile grips both sides of the rafter or truss at once, reducing hardware count and installation time on roof framing and high-wind construction projects
• Built for demanding environments - the ZMAX coating goes beyond standard galvanization, making this hurricane tie a reliable choice for exterior applications and contact with pressure-treated lumber
• Versatile installation options - compatible with inside or outside wall placement and inward- or outward-facing flanges, so it adapts to a variety of framing conditions from deck joists to rafters without special modifications
• Engineered for uplift and lateral resistance - the embossed steel profile adds stiffness at critical stress points, giving builders a connector specifically designed to perform under the forces that matter most in wind and seismic zones

Frequently Asked Questions

What makes the H1AZ different from a single-sided hurricane tie?

The H1AZ is a U-shaped tie that holds the rafter or truss on both sides simultaneously, providing high lateral load resistance and faster installation compared to using two separate single-sided ties.

Can the H1AZ be installed on either side of the wall?

Yes. The H1AZ can be installed on the inside or outside of the wall, or on both sides, and the flanges can face either inward or outward to accommodate a variety of framing configurations.

Why is ZMAX galvanization important for this hurricane tie?

ZMAX galvanization provides extra corrosion resistance, making the H1AZ suitable for exterior applications and use with treated lumber where standard galvanized finishes may be insufficient.

What fasteners are required to install the H1AZ?

Installation requires either (8) 0.131 x 1-1/2 in. nails or (8) #9 x 1-1/2 in. Strong-Drive SD screws.
