The Simpson BA48 BA Top-Flange Joist Hanger for 4x8 by Simpson Strong-Tie is engineered for both solid sawn lumber and engineered wood applications where reliable, medium-to-high load capacity is required. This top-flange hanger captures the top chord of the joist to prevent rotation, delivering structural integrity with a cost-effective, one-piece construction. The BA series supports flexible nailing options - minimum nailing with positive-angle nailing (PAN) for moderate load conditions, and maximum nailing for higher load demands.

The BA48 is designed for both engineered wood and solid sawn lumber applications. It can carry medium loads with solid sawn lumber and higher loads when used with engineered wood products.

What nailing is required to install the BA48?

Install the BA48 using 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 for higher load demands.

Why does the BA48 not require web stiffeners?

The BA48 features a full-height joist flange that captures the top chord of the joist. This design prevents rotation and eliminates the need for web stiffeners, simplifying installation.

What corrosion protection does the BA48 have?

The BA48 is coated with a G90 zinc galvanized finish, providing reliable corrosion resistance suitable for typical construction environments.
