Key Features

• Versatile tie plate design - handles splicing and miscellaneous wood-to-wood connections on flat members, making it a go-to choice for both light repairs and heavier structural work
• Staggered nail pattern - distributes fastener load to resist splitting of wood members, resulting in a stronger, more secure joint
• Flanged construction - adds rigidity and support at the connection point, improving overall joint stability
• 20-gauge steel - provides a solid, consistent thickness that balances strength and ease of installation
• G90 zinc galvanized coating - offers enhanced corrosion resistance to help the plate maintain structural integrity when exposed to moisture and demanding jobsite conditions
• Compatible with multiple fastener types - installs with 0.131 in. x 2-1/2 in. nails, 0.131 in. x 1-1/2 in. nails, or #9 Strong-Drive SD screws, giving installers flexibility based on the tools and materials on hand

Why This Product

• Built for broad application - the TPA57 functions equally well for quick light repairs and demanding structural connections, reducing the need to source different hardware for different jobs on the same site
• Engineered to protect the wood - the staggered nail pattern is specifically designed to resist splitting, preserving the integrity of the lumber and the connection over time
• Corrosion-resistant finish for lasting performance - the G90 zinc galvanized coating goes beyond basic protection, making this tie plate a practical choice for projects where moisture exposure is a real concern
