The Simpson TSP 16-Gauge Galvanized Stud-Plate Tie by Simpson is engineered to connect the top plate to either the wall stud or a 2x rafter in wood-frame construction. Installed on the wide face of the 2x stud, the placement keeps the connector clear of wall sheathing for a clean, unobstructed assembly. A top-flange design allows the tie to attach securely to both sill plates and top plates, while 16-gauge steel construction and a G90 zinc galvanized coating deliver lasting structural reliability in demanding framing applications.

Key Features

• Embossment feature provides strength at the bend - reinforces the critical fold point of the connector, maintaining load capacity where stress is highest.
• Optional diamond holes accommodate various uplift capacities with min./max. nailing configurations - gives framers the flexibility to meet a range of load requirements using the same connector.
• Can be installed before or after placement of the wall - accommodates different jobsite sequencing so crews are never forced to work around a rigid installation order.
• Installed on the wide face of the 2x stud - keeps the tie out of the sheathing plane, eliminating fit-up conflicts and speeding up wall assembly.
• Made from 16-gauge steel with a G90 galvanized coating - provides a corrosion-resistant stud plate tie suited for both interior framing and moisture-exposed environments.

Why This Product

• Versatile connection point for wall framing - the TSP handles stud-to-top-plate and stud-to-2x-rafter connections in a single connector, reducing the number of different ties a crew needs on site.
• Sheathing-friendly placement - by sitting on the wide face of the stud rather than the edge, the tie integrates into the framing without creating a bump or gap under wall sheathing.
• Built-in uplift capacity options - the diamond hole pattern lets installers dial in the right nailing configuration for the project's specific uplift demands, keeping the installation code-compliant and efficient.
• G90 galvanized protection on a Simpson-engineered connector - the heavier zinc coating extends the service life of the stud-plate tie in conditions where bare or lightly coated steel would be prone to early corrosion.

Frequently Asked Questions

What is the primary purpose of the Simpson TSP Stud-Plate Tie?

The TSP is designed for connecting the top plate to either the wall stud or a 2x rafter. Its top-flange design allows it to securely attach to both sill plates and top plates in wood-frame construction.

Where is the TSP installed on the wall framing?

The TSP is installed on the wide face of the 2x stud. This placement is intentional to avoid interference with sheathing applied to the wall assembly.

Can the TSP be installed after a wall has already been erected?

Yes. The TSP can be installed either before or after placement of the wall, providing flexibility during the construction process.

What fasteners are required to install the Simpson TSP?

The TSP is installed with 10d x 1-1/2 in. nails to the rafter/truss and 10d common nails to the plates. The optional diamond holes accommodate various uplift capacities with minimum and maximum nailing configurations.
