The Simpson Strong-Tie BA38 is a top-flange joist hanger engineered for both engineered wood and solid sawn lumber applications. Designed to deliver reliable performance across a range of load conditions, this hanger supports medium loads with solid sawn lumber and higher loads when paired with engineered wood products. The BA series features minimum nailing with positive-angle nailing (PAN) for moderate load conditions, as well as maximum nailing capability to support higher loads - making it a versatile, dependable choice for structural framing projects requiring a nominal 3x8 joist size.

Key Features

• Cost-effective one-piece design compared to welded hangers, reducing material and labor costs
• Full-height joist flange that captures the top chord of the joist to prevent rotation and eliminate the need for web stiffeners
• Positive-angle nailing (PAN) supports both minimum and maximum nailing configurations to target a wide range of load conditions
• 12-gauge steel construction for strength and structural integrity
• Zinc Galvanized (G90) finish for corrosion resistance in demanding environments
• Fits nominal 3x8 joist size for precise, secure connections
• Available for special order to accommodate sloped and/or skewed members

Approved Applications

• Engineered wood products - supports higher load conditions when used with LVL, LSL, PSL, or I-joist applications
• Solid sawn lumber - carries medium loads in standard framing applications
• Nominal 3x8 joist connections requiring a top-flange hanger with anti-rotation capability
• Structural framing where web stiffeners would otherwise be required, eliminated by the full-height joist flange design

Installation

Install 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. Refer to Simpson Strong-Tie load tables for minimum and maximum nailing schedules based on required load conditions.

Options

• Other widths are available; specify W dimension (the minimum W dimension is 1 9/16").
  
• For modified hangers, fastener quantity listed in tables may need to increase depending on joist size, skew and slope. All modified hangers are 12 ga.
• Hangers may be modified for slopes and/or skews up to 45 deg.. The top flanges may be sloped as much as 35 deg. and may be open or closed up to 30 deg.. See Modifications and Associated Load Reductions under Specifications

Frequently Asked Questions

What joist size is the BA38 designed to fit?

The BA38 is designed for a nominal 3x8 joist size, providing a precise, secure connection for that member dimension in both engineered wood and solid sawn lumber applications.

What nails should be used to install the BA38?

Install the BA38 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.

Can the BA38 be used for sloped or skewed framing applications?

The standard BA38 is designed for typical framing configurations, but it is available for special order to accommodate sloped and/or skewed members when your project requires angled connections.

What material and coating is used on the BA38, and why does it matter?

The BA38 is made from 12-gauge steel and features a Zinc Galvanized (G90) finish, which provides corrosion resistance in demanding environments and contributes to its long-term structural reliability.
