Key Features

Uplift Resistance

Built to reinforce the rafter or truss to top plate connection where wind loads matter. The H2.5A helps create a continuous load path so uplift and lateral forces are transferred into the framing instead of pulling connections apart.

18 Gauge Steel Body

The 18 gauge galvanized steel construction gives this hurricane tie the strength needed for moderate-load roof framing connections while holding up in typical wood construction environments.

No Left or Right Part

The symmetrical single-sided design means you do not need separate left-hand and right-hand versions. That makes stocking simpler and helps avoid grabbing the wrong connector during framing.

Overview

The Simpson Strong-Tie H2.5A hurricane tie is a single-sided wood connector used to secure a rafter or truss to the wall top plate. This is a hurricane tie designed for fastening wood-to-wood roof framing connections. For builders, framers, and remodelers working in wind- and seismic-conscious construction, this connector matters because it helps resist both uplift and lateral forces at one of the most important joints in the roof system. Model Number: H2.5A.

In practical terms, the H2.5A is meant for moderate-load rafter or truss-to-top-plate connections. Simpson Strong-Tie lists allowable loads for the H2.5A at up to 625 lb uplift and 450 lb lateral for DF/SP, and up to 540 lb uplift and 385 lb lateral for SPF/HF, with the listed installation schedule. That is the kind of information that matters when you are tying the roof system into the wall assembly and you need a connector that is purpose-built for uplift resistance instead of relying on toenails alone.

The design is simple, and that is part of why it works so well. The connector is made from 18 gauge galvanized steel and uses a narrow 1-3/8 inch width with a 6 inch overall height, so it fits common framing layouts without taking up extra space. The bend-line embossments strengthen the connection, and the top flange includes an arrow line indicator to help with correct installation orientation. Those little design touches save time because they reduce guesswork when you are moving fast on a framing job.

Another real advantage is the symmetrical design. You do not need separate right and left parts, which keeps ordering and jobsite organization easier. If you have ever burned time sorting hardware buckets or realized the box on site is full of the wrong hand, you already know why this matters. One part covering both orientations is just easier to live with.

The Simpson Strong-Tie H2.5A hurricane tie is also built around a defined fastening schedule. Simpson specifies installation with (10) 0.131 inch x 2-1/2 inch nails or (10) #9 x 1-1/2 inch Strong-Drive SD screws, and the load table also references SD9112 fasteners. That matters because connector performance depends on using the correct fasteners and the full fastener count. With structural connectors like this, the connector and the fastener schedule work together as one system.

For jobsite use, the main thing to know is that this connector helps build a continuous load path, but it is not a substitute for every other framing requirement. Simpson specifically notes that hurricane ties do not replace solid blocking, and cautions against fastening through truss plates from behind when installing on plated trusses. That is the kind of detail that keeps a good connector from being misused in the field.

Who should buy it? This is a solid fit for framers, roofers, general contractors, deck and porch builders, and serious DIY users doing code-conscious roof framing or reinforcement work. If you need a compact rafter tie for wood-to-wood fastening and want a proven connector from a brand that lives in structural hardware, the H2.5A is the straightforward choice. It is not flashy, and it does not need to be. It is the kind of part that quietly makes the structure better.

See the Connection in Real Framing

This is where the connector earns its keep. Installed at the rafter-to-plate joint, it reinforces a critical roof framing connection that sees uplift and side load during high wind events.

• Designed for wood-to-wood fastening at the rafter or truss to top plate connection
• Single-sided layout keeps the connector compact and easy to position

Simple Shape, Less Guesswork

The H2.5A keeps things straightforward. Its symmetrical design means there is no separate right-hand or left-hand version to stock, sort, or accidentally install in the wrong place.

• Embossments in the bend line strengthen the formed section
• Top flange arrow line indicator helps with correct installation orientation

Install It on Opposite Sides

Placement matters with structural connectors. The installation illustration shows the intended opposed-side arrangement at the wall top plate connection, which is important for the connector to perform as designed.

• Use all specified fasteners for the published load values
• Do not treat hurricane ties as a replacement for solid blocking

Why the Simpson Strong-Tie H2.5A Hurricane Tie Still Gets the Nod

This is the kind of connector pros buy because it solves a real framing problem without adding drama to the install.

• Who it’s for: Framers, builders, remodelers, and serious DIY users tying rafters or trusses into wall top plates in wood construction.
• Why it stands out: You get a compact 18 gauge connector with published uplift and lateral values, a symmetrical no-left/no-right design, and small details like bend embossments and an installation indicator that actually help on the job.
• Worth knowing: This is not a generic strap you slap on with whatever fasteners are in the pouch. Use the specified fasteners and install it the way Simpson calls out if you want the connector to do its job.

Common Questions

• What is the H2.5A used for? It is used to fasten a wood rafter or truss to the wall top plate and help resist uplift and lateral loads.
• Do I need separate left-hand and right-hand parts? No. The H2.5A has a symmetrical design, so separate right and left parts are not needed.
• What material is it made from? The standard H2.5A model is made from 18 gauge galvanized steel with a G90 zinc coating.
• Can I use any fastener I want? No. Simpson specifies using all required fasteners and following the listed fastener schedule to achieve the published load values.
