The Simpson Strong-Tie BP 1-1/2HDG Bearing Plate is a structural plate washer engineered to distribute concentrated compressive forces between two structural elements at critical load-bearing connections. With a 3 x 3 inch square footprint and 3/8 in. thickness, it provides a substantially greater bearing surface than standard-cut washers, making it a dependable choice for shearwall applications and general load-transfer connections where a wider contact area is required for structural integrity.

Key Features

• Greater bearing surface than standard-cut washers - distributes compressive forces across a wider area, reducing localized stress at critical structural connections
• Hot-Dip Galvanized coating - delivers higher corrosion resistance compared to standard finishes, supporting reliable long-term performance in demanding or exposed environments
• 3 x 3 in. square plate with 3/8 in. thickness - provides a robust, rigid platform for transferring concentrated loads between structural members without deformation under pressure
• 1 9/16 in. hole sized for a 1 1/2 in. bolt - ensures a precise, compatible fit at the fastener point, maintaining proper alignment and load transfer at the connection
• Approved for shearwall applications - designed to be positioned with the plate edge within 1/2 in. of the sheathed edge of the sill plate, meeting specific shearwall installation requirements for single- and double-sheathed walls

Why This Product

• Built for structural load transfer - where a standard-cut washer leaves too small a bearing surface, this plate washer steps in to spread compressive forces across a full 3 x 3 in. footprint, helping protect the integrity of the connection over time
• Corrosion-resistant by design - the Hot-Dip Galvanized finish makes this plate washer suitable for applications where exposure to moisture or harsh conditions is a concern, supporting durability without requiring additional protective treatment
• Versatile across key structural applications - from shearwall sill plate connections to general compressive load-transfer points, this bearing plate covers a range of demanding connection scenarios in one straightforward product
• No washer required with standard BP bearing plates - simplifying installation by eliminating an extra component at the connection, saving time and reducing the chance of improper assembly

Approved Applications

• Load distribution at critical structural connections where concentrated compressive forces must be transferred between two structural elements
• Shearwall applications - position the edge of the plate washer within 1/2" of the sheathed edge of the sill plate
• Suitable for use wherever a greater bearing surface than a standard-cut washer is required

Installation Notes

• For shearwall applications, position edge of plate washer within 1/2" of sheathed edge of sill plate.
• BPS-6 plate washers are sized to accommodate the 1/2" from the sheathed edge in single- and double-sheathed 2x6 walls.
• A standard-cut washer is required when used with BPS slotted bearing plates. A washer is not required when used with standard BP bearing plates.

Options

• Available in Hot-Dip Galvanized (HDG) for higher corrosion resistance
• Also available in black powder coat finish

Frequently Asked Questions

What bolt size is the BP 1-1/2HDG designed to work with?

The BP 1-1/2HDG is designed for use with a 1-1/2 inch diameter bolt. The plate features a 1-9/16 inch hole to accommodate that bolt size.

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

The BP 1-1/2HDG provides a greater bearing surface than standard cut washers. Its 3 x 3 inch square footprint and 3/8 inch thickness allow it to more effectively distribute concentrated compressive forces between two structural elements at critical connections.

What corrosion protection does the BP 1-1/2HDG have, and is another finish available?

The BP 1-1/2HDG features a Hot-Dip Galvanized (HDG) coating, which provides higher corrosion resistance for use in demanding environments. For applications where a different aesthetic or coating is preferred, the bearing plate is also available in a black powder coat finish.

How should the BP 1-1/2HDG be positioned in shearwall applications?

In shearwall applications, the edge of the plate washer should be positioned within 1/2 inch of the sheathed edge of the sill plate to ensure proper load transfer at the connection.
