The Simpson Strong-Tie Bearing Plate BP 1-1/4 is a 3 in. x 3 in. x 3/8 in. structural bearing plate engineered to provide a greater bearing surface than standard-cut washers, helping to distribute load at critical connections. Sized for a 1-1/4 in. diameter bolt with a 1-5/16 in. hole, this plate works by transferring concentrated compressive forces between two structural elements, making it a dependable choice for demanding structural applications including shearwall anchor bolt connections and other locations where standard-cut washers fall short.

Key Features

• Greater bearing surface than standard-cut washers - spreads load more effectively at critical connections, reducing stress concentrations that could compromise structural integrity
• Transfers concentrated compressive forces between two structural elements - provides reliable load path continuity at connections where performance cannot be compromised
• 1-5/16 in. hole sized for a 1-1/4 in. diameter bolt - ensures a proper, snug fit without the need for an additional standard-cut washer, simplifying installation
• No additional standard-cut washer required - each anchor bolt is tightened with a nut and washer using the bearing plate itself, streamlining the fastening process and reducing hardware
• Available with a hot-dip galvanized (HDG) coating - offers higher corrosion resistance for installations exposed to the elements, extending the service life of the connection

Why This Product

• Built for connections where standard washers are not enough - this bearing plate is specifically designed for critical structural connections and shearwall applications where a standard-cut washer cannot provide adequate bearing surface, giving builders and engineers a code-appropriate solution
• Simplifies installation without sacrificing performance - because no additional washer is needed alongside this plate, installers work with fewer components while still achieving a properly loaded, secure anchor bolt connection
• Corrosion resistance is available when the application demands it - the optional hot-dip galvanized coating makes this plate a practical choice for exposed or moisture-prone environments where long-term durability of the structural connection matters
• Trusted Simpson Strong-Tie engineering for load-critical work - backed by a manufacturer with a recognized reputation in structural connectors, this bearing plate is suited for projects where reliable load distribution between structural elements is essential

Frequently Asked Questions

What is the purpose of the BP 1-1/4 Bearing Plate?

The BP 1-1/4 is designed to provide a greater bearing surface than standard-cut washers and help distribute the load at critical connections. It works by transferring concentrated compressive forces between two structural elements.

What bolt diameter is this bearing plate designed for?

This bearing plate is designed for use with a 1-1/4" diameter bolt and features a 1-5/16" hole to accommodate it.

Is an additional washer required when using the BP 1-1/4?

No. No additional standard-cut washer is required. Each anchor bolt should be tightened with a nut and washer using the bearing plate itself.

Is a corrosion-resistant version of the BP 1-1/4 available?

Yes. The BP 1-1/4 may be ordered with a hot-dip galvanized (HDG) coating to protect the plate from corrosion when exposed to the elements.
