The Simpson Bearing Plate with 7/8 in. Bolt Diameter, 3 in. x 3 in. is a structural load-distribution plate built to outperform standard cut washers at critical connections. Engineered from 5/16 in. uncoated steel, this bearing plate delivers a broader contact surface that helps strengthen the connection and spread load more evenly - making it a trusted choice for foundation anchor bolt applications where reliable load transfer is essential.

Key Features

• 7/8 in. bolt hole diameter - fits 7/8 in. anchor bolts precisely, ensuring a secure and properly aligned connection without modification
• 3 in. x 3 in. plate size - provides a significantly larger bearing surface than a standard cut washer, reducing concentrated stress at the connection point
• 5/16 in. steel construction - delivers the thickness and rigidity needed to handle demanding structural loads at foundation connections
• Uncoated steel material - keeps the plate ready for field-applied coatings or use in dry interior applications where additional finishing is handled on site

Why This Product

• Built for load distribution at high-stress connections - the plate is specifically designed to strengthen and distribute load at critical structural points, addressing the limitations of standard cut washers in foundation anchor bolt applications
• Greater bearing surface where it matters most - the 3 in. x 3 in. footprint spreads force over a wider area than a typical washer, helping protect the surrounding substrate and maintain connection integrity over time
• Made in the United States to Simpson standards - produced domestically under Simpson quality control, giving contractors and builders confidence in consistent dimensional accuracy and material performance
• A direct, purpose-built replacement for cut washers on anchor bolts - engineered specifically for foundation anchor bolt use, so there is no need to improvise with general-purpose hardware at structural connection points
