The Simpson DJT14Z Deck Joist Tie is a Simpson engineered connector designed to securely attach 2x deck joists to the side of 4x or larger support posts. Built from 14-gauge steel with ZMAX galvanization, this deck joist tie delivers a reliable framing connection that outperforms nails or screws alone and eliminates the labor of through-bolting - making it a practical choice for exterior deck construction and pressure-treated lumber applications where durability and corrosion resistance matter.

Key Features

• Connects a 2x member (typically a beam) to the side of the post - provides a secure, structurally engineered lateral connection at the post face, replacing makeshift fastening methods
• Suitable for nominal 2x4 minimum cross member and nominal 4x4 minimum post - fits the dimensional lumber most commonly used in residential and light commercial deck framing
• Stronger than nails or screws, easier than through-bolting - gives builders a connection upgrade without the time and tooling that full through-bolt installation requires
• Made from 14-gauge steel - the heavier gauge construction contributes to a load-rated, rigid connection that holds up under the demands of structural framing
• ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications - the enhanced coating stands up to the chemicals in pressure-treated lumber and outdoor moisture exposure, helping the connector last for the life of the deck

Why This Product

• Engineered specifically for deck joist-to-post connections - rather than improvising with toe-nails or field-fabricated hardware, this connector is purpose-built and tested for attaching 2x joists to the side of 4x or larger posts, giving you a predictable, code-friendly result on every install
• Flexible fastening options keep the job moving - the DJT14Z accepts 16d common nails, #10 x 2-1/2 in. Strong-Drive SD screws, or 5/8 in. diameter machine bolts, so crews can use the fastener that fits their tools and project requirements without compromising the connection
• ZMAX coating is built for the harshest outdoor conditions - where standard galvanized hardware can corrode quickly against ACQ or other treated lumber, the ZMAX finish provides the extra protection that exterior deck framing demands
• Simpson quality and consistency on every unit - Simpson connectors are engineered, tested, and manufactured to strict quality standards, so the DJT14Z you install today performs the same as the one you installed on the last job

Frequently Asked Questions

What size members is the DJT14Z designed to work with?

The DJT14Z is suitable for a nominal 2x4 minimum cross member (typically a 2x deck joist) and a nominal 4x4 minimum post.

What fasteners can be used to install the DJT14Z?

The DJT14Z can be installed with 16d common nails, #10 x 2-1/2 in. Strong-Drive SD screws, or 5/8 in. diameter machine bolts. It is recommended to install the connector on the post first.

Why is ZMAX galvanization important for this connector?

ZMAX galvanization provides extra corrosion resistance, making the DJT14Z well-suited for exterior applications and use with pressure-treated wood where standard galvanization may not offer sufficient protection.

Is the DJT14Z stronger than a nailed or bolted connection alone?

Yes. The DJT14Z is engineered to provide a connection that is stronger than nails or screws alone and easier to install than through-bolting, while still offering the option to use bolts for added strength when required.
