The Simpson SPH8 Heavy-Duty Stud Plate Tie is a load-rated, heavy U-shaped strap engineered by Simpson as a stud-to-plate connection built to resist roof uplift. Its horizontal portion bears directly against wood wall top plates or sill plates, while two vertical legs nail to the edges of a wood stud, creating a secure structural connection that resists wind and seismic forces. Cost-effective and straightforward to integrate, this galvanized tie is designed to be installed before wall placement, making it a practical choice for framing contractors and builders seeking reliable uplift resistance without added complexity.

Key Features

• Load rated - gives builders and inspectors confidence that the connection meets defined structural performance requirements.
• Designed to resist wind and seismic forces - engineered for demanding structural applications where roof uplift resistance is critical to building safety.
• Does not require top or bottom track attachment - simplifies installation and reduces labor, with no additional hardware needed at the track.
• Heavy U-shaped strap stud-to-plate design - horizontal portion bears against the wall plate while two vertical legs nail to stud edges, forming a strong mechanical connection between framing members.
• Made from 18-gauge steel - provides the structural strength and rigidity needed for heavy-duty framing connections.
• Zinc Galvanized, G90 coating - delivers extra corrosion resistance to help maintain long-term performance in challenging environments.
• Nominal stud size 2x and nominal plate width 8x - sized to fit standard dimensional lumber, making compatibility with common framing materials straightforward.

Why This Product

• Purpose-built uplift resistance - the heavy U-shaped strap design is specifically engineered as a stud-to-plate connection to resist roof uplift, addressing one of the most critical structural concerns in wind- and seismic-prone construction.
• Faster, cleaner installation - because the SPH8 does not require top or bottom track attachment and is installed before wall placement, it fits naturally into standard framing workflows without disrupting the construction sequence.
• Durable G90 galvanized protection - the Zinc Galvanized, G90 finish goes beyond basic corrosion resistance, helping this stud-to-plate tie hold up in demanding jobsite and long-term service conditions.
• A cost-effective structural solution from a trusted framing hardware brand - Simpson designed this heavy-duty tie to deliver load-rated wind and seismic resistance without overcomplicating the installation, making it a smart value choice for residential and commercial framing projects alike.
