The Simpson BA7.12/18 is a top-flange joist hanger designed for double 3-1/2 in. x 18 in. engineered wood and solid sawn lumber connections. Built as a cost-effective, one-piece alternative to welded hangers, the BA series handles a range of load demands - minimum nailing with positive-angle nailing (PAN) targets moderate load conditions, while maximum nailing supports higher load requirements. The full-height joist flange captures the top chord of the joist, preventing rotation and eliminating the need for web stiffeners, making this hanger a dependable choice for medium to higher load-bearing framing assemblies.

Key Features

• One-piece construction - eliminates the added cost and complexity of welded hangers while maintaining structural reliability across load conditions
• Full-height joist flange - captures the top chord of the joist to prevent rotation and remove the need for web stiffeners, simplifying installation and reducing material requirements
• Positive-angle nailing (PAN) support - allows minimum nailing for moderate load conditions and maximum nailing for higher load demands, giving installers flexibility to match the nailing schedule to the job
• Compatible with engineered wood products and solid sawn lumber - carries medium loads with solid sawn lumber and higher loads with engineered wood products, broadening its range of framing applications
• 12-gauge steel construction - provides the structural strength needed for demanding joist and beam connections in residential and commercial framing
• G90 zinc galvanized finish - delivers extra corrosion resistance, making this hanger suitable for applications where moisture exposure is a concern
• Available modified for sloped and/or skewed members - accommodates non-standard framing conditions without requiring a completely different hanger, supporting greater design flexibility

Why This Product

• Versatile load handling in a single hanger - by supporting both moderate and higher load conditions through adjustable nailing schedules, the BA7.12/18 reduces the need to source multiple hanger types for different areas of the same project
• Rotation resistance without added hardware - the full-height joist flange prevents joist rotation and eliminates web stiffeners, cutting down on installation time and the number of components needed on site
• Works with today's most common engineered lumber - purpose-designed for double 3-1/2 in. x 18 in. engineered wood products, this hanger aligns with modern framing practices that rely on LVL, PSL, and similar EWP members for longer spans and heavier loads
• Corrosion-resistant finish for lasting performance - the G90 galvanized coating provides extra protection against rust and deterioration, helping maintain connection integrity in demanding environments over the life of the structure

Frequently Asked Questions

What size member is the BA7.12/18 designed to support?

The BA7.12/18 is designed for a double 3-1/2 in. x 18 in. member. It is compatible with both engineered wood products and solid sawn lumber, supporting medium loads with solid sawn lumber and higher loads when used with engineered wood.

What nails should be used to install the BA7.12/18?

Install the BA7.12/18 with 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 hanger supports both minimum nailing with positive-angle nailing (PAN) for moderate load conditions and maximum nailing configurations for higher load demands.

Does the BA7.12/18 require web stiffeners?

No. The BA7.12/18 features a full-height joist flange that captures the top chord of the joist, which prevents rotation and eliminates the need for web stiffeners.

What material and coating is used on the BA7.12/18?

The BA7.12/18 is constructed from 12-gauge steel and features a G90 zinc galvanized coating for enhanced corrosion resistance. This one-piece design offers a cost-effective alternative to welded hangers.
