The Simpson ML23SS 2 in. x 3 in. 12-Gauge Stainless-Steel Medium L Angle is a structural connector from Simpson built to deliver reliable 90 deg. corner connections in medium and heavy-duty framing and woodworking applications. Formed from 12-gauge stainless steel, it provides the corrosion resistance required for exterior builds and projects involving pressure-treated or chemically treated lumber. Staggered fastener holes minimize wood splitting during installation, while an opposing hole pattern supports back-to-back installation without fastener interference - keeping corners consistently straight and square.

Key Features

• 90 deg. connection for medium and heavy-duty applications - creates a rigid, load-bearing corner joint that outperforms angled nailing or screw fastening alone
• Stronger than angled nailing or screw fastening - provides a more secure structural connection, reducing the risk of joint failure over time
• Staggered fastener holes - distributes fastener load across the wood grain to minimize splitting and make installation cleaner and more reliable
• Opposing hole pattern - allows back-to-back installation without fastener interference, expanding how and where the connector can be used
• 12-gauge stainless-steel construction - combines substantial thickness with extra corrosion resistance, making it well-suited for exterior environments and treated-wood applications
• Compatible with Strong-Drive SDS Heavy-Duty Connector screws - designed to work with 1/4 in. x 1 1/2 in. stainless-steel SDS screws for a fastener-to-connector pairing that preserves corrosion resistance throughout the assembly

Why This Product

• Built for demanding conditions - stainless-steel construction delivers extra corrosion resistance beyond standard finishes, making this angle a dependable choice for exterior framing and projects where treated lumber is involved
• A structurally superior alternative to toenailing - the 90 deg. angle connector creates a stronger, more consistent joint than angled nailing or screw fastening, helping ensure corners stay tight and square over the life of the structure
• Installation-friendly design - staggered holes reduce wood splitting risk and the opposing hole pattern enables back-to-back connector placement without fastener conflict, saving time and reducing the chance of installation errors
• Versatile across multiple applications - equally at home in light structural framing, deck construction, and treated-wood builds, this connector adapts to a wide range of 90 deg. connection needs without compromising on strength or durability

Frequently Asked Questions

What fasteners should be used with the ML23SS angle?

Install with 1/4 in. x 1-1/2 in. stainless-steel Strong-Drive SDS Heavy-Duty Connector screws. Always use stainless-steel fasteners with stainless connectors. Fasteners are not provided with the angle.

Why is stainless steel the right choice for exterior or treated-wood applications?

Stainless steel offers extra corrosion resistance compared to standard galvanized finishes, making the ML23SS especially well-suited for exterior environments and applications involving pressure-treated or chemically treated lumber where corrosion is a long-term concern.

How does the ML23SS hole pattern prevent wood splitting?

The fastener holes are staggered across the connector legs, which distributes the load and reduces the likelihood of splitting the wood grain during installation - a common issue when fasteners are driven in a straight line along the wood fiber.

Can two ML23SS angles be installed back to back?

Yes. The opposing hole pattern is specifically designed to allow for back-to-back installation without fastener interference, enabling stronger double-angle connections where the application demands additional load capacity.
