Product Description
The Simpson Strong-Tie SP1Z Stud Plate Tie is a 3-1/2 in. x 5-1/16 in. ZMAX galvanized connector engineered to create a reliable sill-to-stud connection that resists uplift forces from wind and seismic activity. Part of Simpson Strong-Tie's stud-plate tie series, the SP1Z features angled nail holes and strategic embossments that deliver a positive, high-strength connection between nominal 2x studs and bottom plates, making it an ideal choice for both new construction and retrofit applications where extra corrosion resistance is required.

Frequently Asked Questions
- What is the difference between the SP1Z and the SP2 stud plate tie?
- The SP1 is designed for sill-to-stud connections, while the SP2 is intended for double-top-plate-to-stud connections. Both resist uplift, but they are used at different locations within the wall framing assembly.
- What fasteners are required to install the SP1Z?
- Install with (10) 0.148 x 3-in. nails. One of the 0.148 in. x 3 in. stud nails is driven at a 45-degree angle through the stud into the plate for a positive connection.
- Why choose the ZMAX version of the SP1 stud plate tie?
- ZMAX galvanization offers extra corrosion resistance compared to standard galvanized coatings, making the SP1Z the appropriate choice for exterior applications and projects involving treated wood where standard connectors may be susceptible to accelerated corrosion.
- Can the SP1Z be installed in existing construction rather than just new builds?
- Yes. The SP1Z can be used before or after installation, including in retrofit applications, making it a versatile solution for upgrading existing stud-to-plate connections to resist wind and seismic forces.
