The Simpson 5-3/4 in. x 7 in. Tie Plate from Simpson Strong-Tie is a simple, reliable connector built for splicing and reinforcing wood-to-wood connections on flat members. Fabricated from 20-gauge steel with a G90 zinc galvanized coating, this flat tie plate handles a wide range of light repair and structural framing tasks with minimal installation complexity. Whether you are bridging a butt joint, reinforcing a splice, or securing miscellaneous flat-member connections, this plate delivers a consistent, corrosion-resistant hold.

Key Features

• Versatile flat-plate design - suits splicing and miscellaneous wood-to-wood connections across a broad range of framing and repair applications, reducing the need for multiple connector types on a job.
• Optimized for flat-member connections - the profile lays flush against flat lumber faces, keeping the connection low-profile and structurally sound without adding unnecessary bulk.
• Staggered nail pattern - distributes fastener load across the wood grain to resist splitting and maintain a secure, long-lasting connection even under stress.
• Available flat (TP) or flanged (TPA) - gives you the flexibility to match the connector to your application, stepping up to a flanged version when added strength is required.
• 20-gauge steel construction - provides a dependable balance of strength and workability, making the plate easy to fasten while holding up to structural loading demands.
• G90 zinc galvanized coating - delivers extra corrosion resistance for use in exposed or moisture-prone environments where bare steel would degrade over time.

Why This Product

• A trusted connector for everyday framing and repair - Simpson Strong-Tie engineered this tie plate for straightforward wood-to-wood splicing, so contractors and builders get a purpose-built solution rather than a workaround, on projects ranging from light repairs to structural connections.
• Corrosion resistance built in, not added after - the G90 zinc galvanized finish is applied at the manufacturing level, meaning the protection is consistent across the entire plate surface and suited for conditions where moisture exposure is a concern.
• Split-resistant fastening geometry - the staggered nail pattern is a deliberate design choice, not an incidental layout, helping protect the integrity of the wood member while maximizing load transfer through the connection.
• Flexibility to scale up when the job demands it - because the flat TP profile and the flanged TPA version share the same footprint and application logic, you can upgrade to the flanged option for added strength without changing your approach or fastener strategy.
