The Simpson Bearing Plate 3x3x3/8 1-5/16 Inch Hole HDG BP 1-1/4HDG is a hot-dip galvanized structural bearing plate from Simpson engineered to transfer concentrated compressive forces between two structural elements at critical connections. With a 3 x 3 inch footprint and 3/8 inch thickness, this plate provides a significantly greater bearing surface than standard-cut washers, making it a reliable choice for load distribution applications where connection integrity matters most.

Key Features

• 3 x 3 inch bearing surface - delivers a larger contact area than standard-cut washers, spreading compressive loads more effectively across the connection point
• 3/8 inch plate thickness - provides the structural rigidity needed to handle concentrated compressive forces without deflection at demanding load-transfer connections
• 1-5/16 inch hole sized for a 1-1/4 inch diameter anchor bolt - ensures proper fit and accurate load transfer at the bolt connection, reducing installation guesswork
• Hot-dip galvanized coating - offers higher corrosion resistance than standard finishes, keeping the plate performing reliably in moisture-exposed or weathered environments
• Replaces standard-cut washers - purpose-built geometry means builders get a code-suitable bearing plate rather than a makeshift washer solution at critical structural connections

Why This Product

• Built for demanding load distribution - the 3 x 3 inch plate area directly addresses applications where a standard-cut washer simply cannot provide adequate bearing surface, reducing stress concentrations at anchor bolt connections
• Hot-dip galvanized for long-term durability - the HDG coating is specifically suited to installations exposed to moisture or corrosive conditions, helping this structural plate maintain its integrity over the life of the structure
• Precision-sized hole for a 1-1/4 inch anchor bolt - the 1-5/16 inch hole provides the correct clearance for secure, accurate positioning at the connection, supporting proper force transfer without compromise
• Made in the United States by Simpson - a trusted name in structural connectors backs this plate with consistent manufacturing quality, giving builders confidence at every critical connection point

Frequently Asked Questions

What is the hole size on the BP 1-1/4HDG bearing plate?

The BP 1-1/4HDG features a 1-5/16-inch hole, which is designed to accommodate a 1-1/4-inch diameter anchor bolt, providing the proper fit and load transfer at the connection point.

Why choose a hot-dip galvanized bearing plate over a standard finish?

The hot-dip galvanized (HDG) coating provides higher corrosion resistance compared to standard finishes, making the BP 1-1/4HDG well-suited for applications exposed to moisture, weather, or other corrosive conditions where long-term durability is essential.

How does this bearing plate differ from a standard-cut washer?

The BP 1-1/4HDG is specifically designed to replace standard-cut washers by offering a significantly greater bearing surface. Its 3 x 3-inch plate dimensions allow it to distribute concentrated compressive loads more effectively across structural connections than a typical washer can provide.

What are the overall dimensions of the BP 1-1/4HDG?

The BP 1-1/4HDG measures 3 inches wide by 3 inches long with a 3/8-inch thickness, providing a robust and stable bearing surface for structural load-distribution applications.
