Simpson Bearing Plate 5/8" Hole, 3 x 3 Hot-Dip Galvanized BP 5/8-3HDG is a heavy-duty structural bearing plate from Simpson engineered to provide a greater bearing surface than standard cut washers. Built from 3-gauge steel with a hot-dip galvanized finish, this plate is designed to strengthen and distribute load at critical connections - making it a dependable choice for foundation anchor bolt applications where reliable load transfer matters.

Key Features

• 5/8 in. bolt diameter compatibility - fits standard 5/8 in. anchor bolts for a precise, secure fit at foundation connections
• 3 in. x 3 in. footprint - delivers a larger bearing surface than standard cut washers, spreading compressive forces over a wider area to reduce stress concentrations
• 3-gauge steel construction - provides substantial thickness and rigidity to handle demanding structural load requirements at critical connection points
• Hot-dip galvanized coating - offers extra corrosion resistance for exterior and treated-wood applications, helping the plate hold up where moisture exposure is a concern

Why This Product

• Better load distribution than cut washers - the 3 in. x 3 in. plate is specifically designed to strengthen and distribute load at critical connections, reducing the risk of bearing failure at anchor bolt locations
• Purpose-built for foundation anchor bolt use - engineered as a direct replacement for cut washers on foundation anchor bolts, giving structural connections a more robust and reliable bearing solution
• Corrosion resistance where it counts - the hot-dip galvanized finish goes beyond standard coatings to protect against moisture and the chemicals present in treated lumber, extending the service life of the connection
• Trusted Simpson quality, made in the United States - backed by one of the most recognized names in structural connectors, this bearing plate is manufactured to consistent standards for use in demanding structural applications

Frequently Asked Questions

What is the purpose of a bearing plate, and how does it differ from a standard cut washer?

Bearing plates give greater bearing surface than standard cut washers. They are designed to help strengthen and distribute the load at critical connections, making them a more effective solution where concentrated compressive forces need to be spread over a larger area.

Where are these bearing plates typically used?

Bearing plates are typically used on foundation anchor bolts in place of cut washers, providing a more robust connection at these critical structural points.

Why is the hot-dip galvanized (HDG) coating important?

Hot-dip galvanization (HDG) offers extra corrosion resistance for exterior and treated-wood applications. This makes the BP 5/8-3HDG well suited for environments where moisture exposure or contact with treated lumber could accelerate corrosion on uncoated hardware.

What size bolt is this bearing plate designed to accommodate?

This bearing plate is specifically designed for a 5/8 in. bolt diameter. Its 3 in. x 3 in. footprint and 3-gauge steel construction ensure strong, reliable load distribution around that bolt size.
