Product Description
Simpson Strong-Tie BP 1-3/4 Bearing Plate - 1-13/16" Hole, 3" x 3" x 3/8"
The Simpson Strong-Tie BP 1-3/4 is a heavy-duty bearing plate engineered to provide a significantly greater bearing surface than standard-cut washers, helping to distribute loads at critical structural connections. Designed for use with a 1-3/4" bolt diameter, this 3" x 3" plate with a 3/8" thickness works by transferring concentrated compressive forces between two structural elements, reducing stress concentrations and improving overall connection integrity. The BP 1-3/4 is available with a hot-dip galvanized (HDG) coating for superior corrosion resistance in exposed or demanding environments.

Frequently Asked Questions
- What bolt diameter is the BP 1-3/4 designed for, and what is the hole size?
- The BP 1-3/4 is designed for use with a 1-3/4" bolt diameter. The plate features a 1-13/16" hole to accommodate that bolt size.
- How does the BP 1-3/4 differ from a standard-cut washer?
- The BP 1-3/4 provides a significantly greater bearing surface than standard-cut washers at critical connections. Because of this larger surface area - 3" x 3" with a 3/8" thickness - it more effectively distributes concentrated compressive forces between structural elements, reducing stress concentrations and improving overall connection integrity. No additional standard-cut washer is required during installation.
- Is a corrosion-resistant coating option available for the BP 1-3/4?
- Yes. The BP 1-3/4 is available with a hot-dip galvanized (HDG) coating, which provides superior corrosion resistance and makes it suitable for use in exposed or demanding environments.
- What are the overall dimensions of the BP 1-3/4 bearing plate?
- The BP 1-3/4 measures 3" in width, 3" in length, and 3/8" in thickness, with a 1-13/16" hole at its center.
