The Simpson H8Z H8 18-Gauge ZMAX Galvanized Hurricane Tie by Simpson Strong-Tie is engineered to resist high winds and seismic forces by positively connecting trusses and rafters to the top of wall of a structure. Built from 18-gauge steel with a ZMAX galvanized finish, this hurricane tie delivers enhanced corrosion resistance for exterior and treated-wood applications, making it a dependable choice for both solid-sawn and engineered lumber connections across a wide range of projects.

Key Features

• Great for connecting 2x deck joists on top of a perpendicular beam
• Install in pairs on either side of the rafter/truss/joist to provide resistance to uplift and lateral forces
• Use also for a variety of connections where one member crosses another
• Made from 18-gauge steel
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications
• Approved for installation with 10d x 1-1/2 in. nails or #9 x 1-1/2 in. Strong-Drive SD screws
• Flanges can be installed facing either inward or outward

Frequently Asked Questions

What fasteners are required to install the H8Z hurricane tie?

Each tie requires either (10) nails 0.148" x 1-1/2" or (10) #9 x 1-1/2" Strong-Drive SD Connector screws. The tie is approved for installation with load-rated Strong-Drive SD Connector screws.

Why does the H8Z have a ZMAX finish instead of standard galvanization?

The ZMAX galvanized coating provides extra corrosion resistance compared to standard galvanization, making the H8Z specifically suited for exterior applications and use with treated wood where moisture and chemical exposure are concerns.

Should hurricane ties be installed individually or in pairs?

For maximum resistance to uplift and lateral forces, hurricane ties should be installed in pairs on either side of the rafter, truss, or joist.

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 to resist wind and seismic forces, but solid blocking must still be used where required.

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.
