The Simpson Bearing Plate with 5/8 in. Bolt Diameter, 2-1/2 in. x 2-1/2 in., Hot-Dip Galvanized is a heavy-duty steel plate engineered to provide a greater bearing surface than standard cut washers at critical structural connections. Built for use on foundation anchor bolts, it is designed to strengthen and distribute load more effectively than a conventional washer, making it a go-to choice for both residential and commercial structural applications. The hot-dip galvanized finish adds meaningful corrosion resistance, keeping this plate dependable in exterior settings and wherever treated-wood construction calls for compatible hardware.

Key Features

• 5/8 in. bolt diameter compatibility - fits standard 5/8 in. foundation anchor bolts for a secure, properly sized connection without modification.
• 2-1/2 in. x 2-1/2 in. plate footprint - spreads load over a larger surface area than a standard cut washer, reducing stress concentration at the connection point.
• 1/4 in. steel construction - provides the rigidity and structural integrity needed to perform reliably under the demands of load-bearing anchor bolt applications.
• Hot-dip galvanized (HDG) finish - delivers extra corrosion resistance, making this plate well suited for exterior structural use and treated-wood applications where standard coatings may fall short.

Why This Product

• Purpose-built for foundation anchor bolt connections - designed specifically to replace standard cut washers where stronger load distribution is required, giving structural professionals a more robust solution at one of the most critical points in a build.
• Greater bearing surface for safer load transfer - the larger plate footprint actively strengthens the connection by distributing force over a wider area, helping protect the surrounding material from concentrated stress.
• Hot-dip galvanization for long-term durability outdoors - the HDG coating offers a higher level of corrosion protection than standard finishes, making this plate a reliable choice for exterior conditions and treated-wood framing where hardware degradation is a real concern.
• Made in the United States by Simpson - backed by a brand widely trusted in structural connectors and fasteners, this bearing plate is manufactured to consistent quality standards for professional construction applications.

Frequently Asked Questions

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

Bearing plates give a greater bearing surface than standard cut washers. They are designed to help strengthen and distribute the load at critical connections, making them a more robust choice for foundation anchor bolt applications.

What bolt diameter is this bearing plate designed for?

This bearing plate is designed for a 5/8 in. bolt diameter, making it compatible with standard 5/8 in. foundation anchor bolts.

Why is a hot-dip galvanized finish important for this bearing plate?

Hot-dip galvanization (HDG) provides an extra layer of corrosion resistance, making this bearing plate well suited for exterior applications and treated-wood construction where exposure to moisture or corrosive chemicals is a concern.

What are the dimensions and material thickness of the BP 5/8HDG?

The BP 5/8HDG measures 2-1/2 in. x 2-1/2 in. and is made from 1/4 in. steel, providing a sturdy, rigid plate capable of distributing compressive forces effectively at structural connection points.
