The Simpson BP 5/8 Bearing Plate (2-1/2 in. x 2-1/2 in.) is a structural steel bearing plate engineered to deliver a greater bearing surface than standard cut washers at critical load-bearing connections. Built by Simpson from 1/4 in. uncoated steel, this bearing plate is designed to help strengthen and distribute compressive loads where it matters most - making it a reliable choice for foundation anchor bolt installations and other demanding structural connections that require enhanced load transfer.

Key Features

• 5/8 in. bolt diameter compatibility - sized to fit 5/8 in. foundation anchor bolts directly, making integration into standard anchor bolt assemblies straightforward and precise
• 2-1/2 in. x 2-1/2 in. plate dimensions - the wider footprint spreads compressive forces across a larger surface area compared to a standard cut washer, reducing stress concentration at the connection point
• 1/4 in. thick steel construction - the substantial plate thickness provides a rigid, stable platform that resists bending or deflection under load at critical structural connections
• Uncoated steel material - delivers a solid, consistent steel substrate suited for structural applications where the installer or contractor will apply their own finish or coating as required by the project

Why This Product

• Proven load distribution advantage - bearing plates are specifically designed to provide a greater bearing surface than standard cut washers, helping to strengthen connections and distribute loads more effectively where anchor bolts meet structural elements
• Purpose-built for foundation anchor bolt applications - this plate is engineered as a direct replacement for cut washers on foundation anchor bolts, addressing one of the most critical and load-intensive connection points in structural construction
• Heavy-gauge steel for structural confidence - the 1/4 in. thick uncoated steel construction ensures the plate holds its form and function under the concentrated compressive forces typical of anchor bolt and structural bearing connections
• Made in the United States by a trusted structural hardware brand - produced domestically and backed by Simpson's reputation for structural connection hardware, giving contractors and engineers confidence in material quality and dimensional consistency

Frequently Asked Questions

What is the advantage of using a bearing plate over a standard cut washer?

Bearing plates provide a greater bearing surface than standard cut washers, which helps strengthen and distribute the load more effectively at critical connections. This makes them better suited for demanding structural applications such as foundation anchor bolt installations.

What bolt diameter is the BP 5/8 designed to fit?

The BP 5/8 bearing plate is designed for use with a 5/8 in. bolt diameter, making it compatible with correspondingly sized foundation anchor bolts.

What are the dimensions and thickness of this bearing plate?

The BP 5/8 measures 2-1/2 in. x 2-1/2 in. and is made from 1/4 in. thick steel, providing a robust and rigid platform for load distribution at structural connections.

What material and finish does the BP 5/8 have?

The BP 5/8 is constructed from uncoated steel with no additional coating or finish applied. It is best suited for applications where corrosion exposure is limited or where a coating will be applied on-site.
