Product Description
The Simpson SP6Z 5-9/16 in. x 7-3/4 in. ZMAX Galvanized Stud-Plate Tie by Simpson is a U-shaped structural connector engineered to create a dependable stud-to-plate connection that resists uplift in wood-framed walls. 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 - forming a secure, load-rated assembly designed to hold up against wind and seismic forces. A cost-effective choice for framing professionals, this tie is intended to be installed before wall placement, and its ZMAX galvanized coating makes it well-suited for exterior and treated-wood applications where long-term corrosion resistance matters.
Key Features
- Load rated - provides verified, code-relevant structural performance so builders and inspectors can rely on consistent results.
- Designed to resist wind and seismic forces - adds critical uplift resistance at the stud-to-plate connection, helping wood-framed walls meet structural requirements in high-load conditions.
- Does not require top or bottom track attachment - simplifies the installation process and reduces additional hardware needs on the job site.
- Compatible with a nominal 2x stud and nominal 6x plate - sized specifically for this common member combination, ensuring a precise fit without modification.
- Made from 20-gauge steel - delivers a balance of strength and workability suitable for standard wood-framing applications.
- ZMAX galvanization offers extra corrosion resistance - performs reliably in exterior environments and alongside treated lumber where standard coatings may break down prematurely.
Why This Product
- Built for demanding environments - ZMAX galvanization goes beyond standard corrosion protection, making this tie a dependable choice wherever treated wood or exterior exposure is part of the build.
- Engineered for wind and seismic uplift resistance - the U-shaped form is purpose-designed to hold studs firmly to plates under the lateral and uplift forces that framing connections are most commonly stressed by.
- Install-before-placement design saves time - because the SP6Z is applied before the wall goes up, it fits naturally into standard framing workflows without requiring disruptive retrofit steps.
- No track attachment needed - fewer installation dependencies mean fewer opportunities for error and a cleaner, faster tie-in between stud and plate.
