The Simpson BA412 BA Top-Flange Joist Hanger for 4x12 is a heavy-duty framing connector from Simpson engineered for both engineered wood products and solid sawn lumber applications. This top-flange hanger delivers medium load capacity with solid sawn lumber and higher load capacity with engineered wood products, making it a dependable choice across a wide range of structural framing conditions. The BA series supports minimum nailing with positive-angle nailing (PAN) to address moderate load conditions and maximum nailing configurations to handle higher loads, giving builders the flexibility to match fastening patterns to actual project demands.

Key Features

• Cost-effective one-piece design - eliminates the added expense and variability of welded hangers, delivering consistent, factory-formed geometry every time
• Full-height joist flange - captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners, reducing labor and material costs on the job site
• Top-flange mounting - the hanger seats over the header for a secure, load-transferring connection that keeps the beam flush and properly aligned during installation
• 14-gauge steel construction - provides the structural strength needed to carry medium-to-higher loads for 4x12 framing members in demanding applications
• Zinc Galvanized G90 finish - protects the connector from corrosion in exposed framing environments, supporting long-term performance in the structure
• Available for sloped and skewed member applications - accommodates non-standard framing angles, giving contractors a path to a code-compliant connection even in complex framing situations

Why This Product

• Handles both lumber types with one connector - whether the project calls for solid sawn lumber or engineered wood products, this top-flange joist hanger adapts to each with appropriate load capacity, reducing the need to source multiple connector types for a single build
• Eliminates web stiffeners by design - the full-height joist flange captures the joist and prevents rotation without any additional blocking or stiffeners, directly cutting installation steps and keeping framing clean
• Flexible nailing options match actual load conditions - with both minimum PAN nailing for moderate loads and maximum nailing for higher loads, the BA412 lets builders right-size the connection rather than over-engineer every joint
• One-piece stamped construction keeps costs predictable - compared to fabricated or welded hangers, the single-piece 14-gauge steel form means no field welding, no assembly, and no inconsistency between connectors across the same framing run

Frequently Asked Questions

What lumber types is the BA412 compatible with?

The BA412 is designed for use with both engineered wood products and solid sawn lumber. It carries medium loads with solid sawn lumber and is capable of supporting higher loads when used with engineered wood products.

What nails are required to install the BA412?

Installation requires 0.162 in. x 3-1/2 in. nails in the header and 0.148 in. x 1-1/2 in. nails in the joist. The BA412 supports minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing for higher load conditions.

Why does the BA412 not require web stiffeners?

The BA412 features a full-height joist flange that captures the top chord of the joist, which prevents rotation. This design eliminates the need for web stiffeners, simplifying installation and reducing material requirements.

What corrosion protection does the BA412 have?

The BA412 is coated with a G90 zinc galvanized finish, which provides reliable corrosion resistance for use in typical framing environments.
