Simpson Strong-Tie A23 Angle is a galvanized framing angle built to reinforce wood-to-wood 90-degree connections in framing, blocking, and general repair work. This is a framing angle designed for fastening wood-to-wood corner connections. Model Number: A23. If you need a simple connector that helps keep corners straight while adding real holding strength, this is the kind of hardware that earns its spot fast.

The A23 is made from 18 gauge steel and sized at 2 in. x 1-1/2 in. x 2-3/4 in. with an 8-hole pattern. In practical terms, that gives you a compact angle that fits common framing situations without taking up much space, while still giving you enough fastener locations to build a more secure joint. Simpson lists this model for fastening wood to wood, and that is exactly where it makes sense: tying members together at a right angle when nails alone are not enough.

One of the main advantages of the Simpson Strong-Tie A23 Angle is consistency. Angled nailing can work, but it depends heavily on access, accuracy, and the person doing the work. A formed steel angle helps you place fasteners in a repeatable pattern and keeps the corner aligned while you build. That matters on repairs, shed framing, utility structures, bracing, and small reinforcement jobs where a sloppy joint turns into movement later.

The G90 zinc galvanized finish adds corrosion resistance for standard applications, which is important for connectors that may live inside walls, near damp lumber, or in spaces that are not perfectly dry year-round. Simpson also notes that some products in this family are offered in higher-corrosion-resistance versions, but this specific A23 variant is the standard galvanized model. For typical interior framing and many general construction uses, that is the right fit.

Fastener choice matters with a connector like this. Lowe's lists installation with 10d x 1-1/2 in. nails or #9 x 1-1/2 in. Strong-Drive SD screws, and Simpson specifically notes to use all specified fasteners. That is not filler language. Connector performance depends on the fastener schedule, so leaving holes empty changes how the angle carries load. Simpson's published allowable load data for the A23 also shows why proper fastening matters, with listed values including 670 lb uplift and 560 lb lateral for DF/SP, and 580 lb uplift and 480 lb lateral for SPF/HF.

This angle is best suited to carpenters, remodelers, deck and shed builders, maintenance crews, and serious DIY users who want a cleaner, more dependable corner connection. It is a small part, but it solves a real problem: making wood joints stronger, straighter, and more repeatable without overcomplicating the job. If your project calls for a compact wood connector for 90-degree fastening and repair work, the Simpson Strong-Tie A23 Angle is a practical choice.

Simpson Strong-Tie A23 Angle Keeps Small Framing Jobs Honest
