The Simpson SP8 Stud Plate Tie is a U-shaped structural connector engineered to create a dependable stud-to-plate connection that resists uplift in wood-framed wall assemblies. Its horizontal portion bears firmly against wood-wall top plates or sill plates, while two vertical legs nail securely to the edges of a wood stud - delivering reliable performance against wind and seismic forces. Made from 20-gauge steel with a G90 zinc galvanized finish, this tie is designed for use with a nominal 2x stud and a nominal 8x plate, and is most effective when installed before wall placement.

Key Features

• Load rated - gives builders confidence that the connection meets defined performance requirements for structural applications.
• Designed to resist wind and seismic forces - provides critical uplift resistance that helps protect wood-framed walls in high-wind and seismic zones.
• Does not require top or bottom track attachment - simplifies the installation process and reduces the number of additional components needed on the job site.
• Compatible with nominal 2x stud and 8x plate - fits standard wood-framed wall members, making it straightforward to incorporate into common construction assemblies.
• Made from 20-gauge steel - delivers structural integrity while keeping the connector lightweight and easy to handle during framing.
• Galvanized (G90) for extra corrosion resistance - the zinc galvanized coating helps the tie hold up in demanding conditions, supporting long-term performance.

Why This Product

• A purpose-built uplift solution for wood-framed walls - the U-shaped design is specifically engineered for stud-to-plate connections, addressing uplift from wind and seismic loads without requiring extra hardware or track attachments.
• Cost-effective when it counts - Simpson designed the SP series as a cost-effective option for stud-to-plate connections, giving contractors a load-rated solution that does not compromise on structural performance.
• Corrosion-resistant construction for lasting reliability - the G90 zinc galvanized finish provides extra corrosion resistance, helping the tie maintain its integrity over the life of the structure.
• Straightforward installation with standard fasteners - the SP8 installs with six nails and goes in before wall placement, fitting naturally into the framing sequence without complicating the workflow.

Frequently Asked Questions

What is the primary purpose of the Simpson SP8 Stud Plate Tie?

The SP8 is designed as a stud-to-plate connection to resist uplift. Its U-shaped form allows a horizontal portion to bear against wood-wall top plates or sill plates while two vertical legs are nailed to the edges of a wood stud, helping the assembly resist wind and seismic forces.

What size stud and plate is the SP8 compatible with?

The SP8 is designed for use with a nominal 2x stud and a nominal 8x plate, making it suitable for standard wood-framed wall assemblies using those member sizes.

What fasteners are required to install the SP8?

Installation requires (6) 0.148 in. x 1-1/2 in. nails. For best results, the tie should be properly installed before the placement of the wall.

Does the SP8 require attachment to a top or bottom track?

No. The SP8 does not require top or bottom track attachment, which simplifies installation and makes it a cost-effective option for stud-to-plate connections in wood-framed walls.
