The Simpson BP5/8SKT Bearing Plate is a heavy-duty plate washer engineered to provide a greater bearing surface than standard-cut washers at critical structural connections. Designed for 5/8 in. diameter anchor bolt applications, this zinc-plated, 3-gauge steel plate transfers concentrated compressive forces between two structural elements - delivering consistent, code-ready performance in shearwall sill plate connections and anchor bolt assemblies where load distribution accuracy is essential.

Key Features

• Greater bearing surface than standard-cut washers - distributes compressive loads more effectively at anchor bolt locations, reducing stress concentration at the connection point
• 3-gauge steel construction with zinc plating - provides heavy-duty strength and corrosion resistance suited for demanding structural applications
• Sized for 5/8 in. anchor bolts with a 4 in. x 2 in. footprint - fits precisely at shearwall sill plate connections where accurate plate washer positioning is critical to assembly performance
• Screws included in the package - eliminates the need to source fasteners separately, keeping your installation workflow efficient
• Made in the United States - supports domestic manufacturing and gives contractors confidence in consistent quality and material traceability

Why This Product

• Purpose-built for shearwall and anchor bolt work - unlike general-purpose washers, this plate washer is specifically engineered for shearwall sill plate connections and structural assemblies where load transfer between two elements must be precise and reliable
• Trusted Simpson engineering - Simpson is a recognized name in structural connectors and fasteners, and the BP5/8SKT carries that same commitment to performance in a straightforward, job-site-ready component
• Complete out of the box - screws are included alongside the bearing plates, so contractors and builders have everything needed for installation without hunting down separate hardware
• Zinc-plated 3-gauge steel for lasting durability - the combination of heavy-gauge steel and a protective zinc coating makes this plate washer a dependable long-term solution at structural connection points subject to compressive loading

Frequently Asked Questions

What size anchor bolt does the BP5/8SKT bearing plate fit?

The BP5/8SKT is designed for a 5/8 in. diameter anchor bolt. Simpson bearing plates are also available in additional sizes to accommodate most common anchor bolt diameters, including 3/8", 1/2", 3/4", 7/8", and 1".

What are the dimensions and material specs of this bearing plate?

The BP5/8SKT measures 4 in. wide by 2 in. long and is constructed from heavy-duty 3-gauge steel with a zinc-plated coating for corrosion protection in standard interior and exterior applications.

How does this bearing plate differ from a standard cut washer?

The BP5/8SKT provides a greater bearing surface than standard cut washers, which allows it to more effectively distribute concentrated compressive forces between two structural elements at critical connection points such as shearwall sill plate and anchor bolt applications.

What is included in the package, and are other finish options available?

Each package includes 50 bearing plates along with screws. For projects requiring higher corrosion resistance, the BP5/8SKT is also available in a hot-dip galvanized (HDG) finish, and a black powder coat finish is available as well.
