The Simpson Strong-Tie SP1 Stud Plate Tie is a 3-1/2 in. x 5-1/16 in. galvanized steel connector engineered to provide a secure sill-to-stud connection that resists uplift forces caused by wind and seismic activity. Part of Simpson Strong-Tie's stud-plate tie series, the SP1 features angled nail holes and formed embossments that deliver a positive, structurally reliable connection between nominal 2x studs and bottom plates - and can be installed in both new construction and retrofit applications.

Frequently Asked Questions

What is the difference between the SP1 and the SP2 stud plate tie?

The SP1 is designed for sill-to-stud connections at the bottom plate to resist uplift, while the SP2 is intended for double-top-plate-to-stud connections. Both ties are part of the Simpson Strong-Tie stud-plate tie series and feature angled holes for a positive connection from the stud to the plates.

What size studs is the SP1 compatible with?

The SP1 stud plate tie is designed for use with nominal 2x member sizes, which are standard framing lumber dimensions used in residential and light commercial construction.

Can the SP1 be installed in existing construction or only during new builds?

The SP1 can be used before or after installation, including in retrofit applications. This makes it suitable for upgrading existing structures to improve resistance to wind and seismic forces without requiring the framing to be disassembled.

What fasteners are required to install the SP1 stud plate tie?

The SP1 is installed with (10) 0.148 x 3-in. nails. One of these nails is driven at a 45 deg. angle through the stud into the plate to ensure a secure, positive connection between the stud and plate members.
