Simpson BP 1/2-3 3 in. x 3 in. Bearing Plate with 1/2 in. Bolt Diameter is a heavy-duty structural plate from Simpson built to provide a greater bearing surface than standard cut washers. Designed to help strengthen and distribute the load at critical connections, this bearing plate is typically used on foundation anchor bolts in place of cut washers - making it a dependable upgrade for structural assemblies where reliable load transfer matters most.

Key Features

• 1/2 in. bolt diameter compatibility - fits standard 1/2 in. foundation anchor bolt applications without modification, simplifying installation at critical connection points
• 3 in. x 3 in. plate dimensions - delivers a broader bearing footprint than a standard cut washer, spreading compressive forces over a wider area to reduce stress concentrations
• 3-gauge steel construction - the heavy gauge thickness provides substantial rigidity and strength, standing up to the demands of structural load-bearing use
• Uncoated steel finish - allows for straightforward field treatment or use in applications where a protective coating will be applied on-site, keeping your finishing options open

Why This Product

• Purpose-built load distribution - unlike standard cut washers, this bearing plate is specifically designed to help strengthen connections and spread loads across a larger surface, reducing the risk of localized failure at anchor bolt connections
• Ideal for foundation anchor bolt applications - engineered as a direct replacement for cut washers on foundation anchor bolts, it addresses one of the most critical connection points in structural assemblies
• Heavy-gauge durability from a trusted structural brand - made from 3-gauge steel by Simpson, this plate brings meaningful thickness and structural integrity to connections where performance cannot be compromised
• Made in the United States - domestic production supports consistent quality standards for a component relied upon in load-bearing structural connections
