The Simpson Strong-Tie LSTA12 Strap Tie is a light-gauge straight strap connector for structural wood framing. This is a strap tie designed for uplift and tension-load wood-to-wood connections. Model Number LSTA12, this connector is made for edge use on 2x members where you need a load-rated tie that installs quickly and gives predictable performance.

What separates the LSTA12 from a generic flat strap is that it is an engineered connector, not just a piece of punched steel. Simpson Strong-Tie rates this series for structural use, and the LSTA12 uses a staggered fastener hole pattern to optimize strength. In practical terms, that means you are not just tying members together, you are using a connector designed to handle uplift and tension forces in the connection.

The 12 inch length and 1-1/4 inch width make this model a practical size for reinforcement and tie applications on standard wood framing members. For the LSTA12 specifically, the published fastening schedule calls for (10) SD9112 screws in Simpson load data, and supplementary product data also lists (10) 0.148 inch x 2-1/2 inch nails as required fasteners. The important takeaway is simple: this connector only performs to published values when the specified fasteners are used in the specified holes.

Material and finish matter on structural hardware, and this model uses 20-gauge steel with a Zinc Galvanized G90 coating. That makes it a solid fit for standard framing environments where corrosion resistance is needed beyond bare steel. It is not listed for treated lumber in the provided product data, so if you are working with pressure-treated stock, you will want to verify the right connector and fastener combination before ordering.

On the job, the design is straightforward and useful. The strap is precut, load-rated, and ready to install without field-fabricating a tie from coil stock. The staggered hole layout helps reduce splitting compared with driving a straight line of fasteners down the same grain path. That saves time and helps the connection go in cleaner, especially when you are working on edges of 2x framing members.

The Simpson Strong-Tie LSTA12 Strap Tie is a good fit for framers, remodelers, and general contractors handling wood-to-wood structural connections in high-wind or uplift-prone areas. It is especially useful when you need a simple straight strap for tying members together across a connection while staying inside an engineered fastening pattern. If you want a small structural connector that is easy to understand, easy to install correctly, and backed by published load information, this is exactly the kind of part you buy.
