The Simpson ML23Z 2 in. x 3 in. 12-Gauge ZMAX Galvanized Medium L Angle from Simpson Strong-Tie is a structural corner connector built for medium and heavy-duty framing applications where joint strength and long-term reliability matter. Engineered to work with Strong-Drive SDS Heavy-Duty Connector screws, this L angle delivers a rigid 90 deg. mechanical connection that outperforms angled nailing or screw fastening alone. Staggered fastener holes reduce the risk of wood splitting, while an opposing hole pattern supports back-to-back installation without fastener interference - giving builders and contractors added flexibility on the job site.

Key Features

• 90 deg. connection for medium and heavy-duty applications - provides a rigid, load-distributing corner joint suited for demanding structural framing tasks
• Stronger than angled nailing or screw fastening - the mechanical connector plate spreads load across multiple fastener points for a more secure, lasting hold
• Consistently straight and strong joints - helps eliminate the guesswork of hand-nailed corners, resulting in cleaner, more accurate framing
• 12-gauge steel construction - delivers the thickness and rigidity needed for structural connections where light-duty hardware falls short
• ZMAX galvanization - offers extra corrosion resistance specifically suited for exterior framing and treated-wood applications where standard galvanized coatings may be insufficient
• Opposing hole pattern - allows back-to-back installation without fastener interference, supporting double-sided connection configurations
• Staggered fastener holes - minimizes wood splitting during installation, preserving the integrity of the connected members

Why This Product

• Built for exterior and treated-lumber environments - the ZMAX galvanized finish provides enhanced corrosion protection beyond standard coatings, making this angle a dependable choice for outdoor structures, decks, and pressure-treated wood framing
• A stronger alternative to traditional fastening methods - by creating a rigid mechanical connection at the corner joint, this L angle delivers greater structural integrity than angled nailing or screw fastening, helping ensure joints stay tight over time
• Designed for installation flexibility - the opposing hole pattern enables back-to-back configurations without fastener conflict, while staggered holes protect the wood, so contractors can adapt the connector to a wider range of job-site conditions
• Versatile connector from a trusted structural hardware brand - Simpson Strong-Tie engineering is reflected in the details of this angle, from the screw-compatible hole sizing to the 12-gauge steel body, making it a practical fit for both professional builders and serious DIYers tackling medium to heavy-duty corner connections

Frequently Asked Questions

What fasteners are recommended for installing the ML23Z?

Install with (4) 1/4 in. x 1-1/2 in. Strong-Drive SDS Heavy-Duty Connector screws per angle (Model: SDS25112, sold separately).

Why is the ML23Z angle stronger than standard nailing or screw fastening?

The ML angle creates a rigid 90 deg. mechanical connection that distributes load across the connector plate and multiple fastener points, which is stronger than angled nailing or screw fastening alone and helps ensure joints are consistently straight and strong.

Is the ML23Z suitable for use with pressure-treated lumber?

Yes. The ZMAX galvanization offers extra corrosion resistance specifically designed for exterior and treated-wood applications, making the ML23Z appropriate for use with treated lumber.

Can two ML23Z angles be installed back to back?

Yes. The ML23Z features an opposing hole pattern that allows for back-to-back installation without fastener interference, providing added flexibility for double-sided connection applications.
