The Simpson H3Z H3 18-Gauge ZMAX Galvanized Hurricane Tie is a single-sided structural connector engineered by Simpson to resist moderate lateral and uplift loads at the rafter/truss-to-top-plate connection. As part of a continuous load path, it helps protect wood-framed structures against wind and seismic forces, making it a go-to choice for rafter tie-downs, truss anchoring, and other crossmember connections where reliable performance is critical. Available in left-hand and right-hand models, the H3Z can be installed in pairs at the same connection point for increased load resistance.

Key Features

• Rafter/truss-to-top-plate connection designed to resist wind and seismic forces - anchors the roof structure to the wall system so uplift and lateral loads are transferred through a continuous load path rather than relying on nails alone.
• Approved for installation with load-rated Strong-Drive SD Connector screws - gives installers a code-recognized screw-fastening option alongside nails, offering flexibility on the jobsite without sacrificing rated performance.
• Versatile crossmember connector - works for a variety of connections where one structural member crosses another, extending its usefulness beyond standard rafter tie applications.
• Made from 18-gauge steel - provides the strength-to-material balance needed for moderate-load rafter and truss connections without unnecessary bulk.
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - the enhanced zinc coating stands up to the corrosive chemistry of pressure-treated lumber and outdoor exposure, helping the connector maintain its structural integrity over time.

Why This Product

• Built for continuous load path construction - the H3Z is specifically designed to work as part of a whole-structure load transfer system, so wind and seismic forces are carried predictably from the roof down through the wall framing rather than concentrated at a single weak point.
• Left- and right-hand models that work in pairs - having both orientations available means the connector fits virtually any framing layout, and pairing them at a single rafter or truss location is a straightforward way to increase resistance without switching to a heavier product.
• ZMAX coating makes it suitable where standard galvanized connectors fall short - for projects using treated lumber or exposed exterior framing, the extra corrosion protection built into the ZMAX finish means the connector is matched to the environment, not just the structural requirement.
• Fastener flexibility with a single SKU - acceptance of both standard nails and Strong-Drive SD Connector screws means contractors are not locked into one fastening method, which can simplify scheduling and tool requirements across different phases of a project.

Frequently Asked Questions

What fasteners are required to install the H3Z hurricane tie?

Each tie requires (8) 0.131 in. x 2-1/2 in. nails or (8) #9 x 1-1/2 in. Strong-Drive SD Connector screws. Use hot-dip galvanized (HDG) nails with ZMAX connector products.

Can the H3Z be used with treated lumber or in exterior applications?

Yes. The ZMAX galvanization offers extra corrosion resistance specifically designed for exterior and treated-wood applications, making it well suited for these environments.

Are left-hand and right-hand models available, and can they be used together?

Yes. The H3Z is available in both left-hand and right-hand models, and both can be installed in pairs at the same rafter or truss connection for increased performance.

Do hurricane ties replace solid blocking?

No. Hurricane ties do not replace solid blocking. They are designed to work as part of a continuous load path system and should be used in conjunction with proper blocking per applicable building requirements.

Note: When installing ties on plated trusses on the side opposite the truss plate, do not fasten through the truss plate from behind. This can force the truss plate off of the truss and compromise truss performance.
