Simpson Bearing Plate 1-1/16" Hole, 3 x 3 x 3/8 (BP 1-3) - is a structural bearing plate manufactured by Simpson Strong-Tie, designed to provide a greater bearing surface than standard-cut washers and help distribute load at critical connections. By transferring concentrated compressive forces between two structural elements, this 3" x 3" x 3/8" plate is an essential component for shearwall and anchor bolt applications where reliable load distribution is required.

Key Features

• Replaces standard-cut washers while providing a greater bearing surface
• Transfers concentrated compressive forces between two structural elements
• Sized for most common anchor bolt sizes: 3/8", 1/2", 5/8", 3/4", 7/8", and 1"
• 1-1/16" hole diameter accommodates a 1" bolt diameter
• May be ordered HDG (hot-dip galvanized) for higher corrosion resistance
• No additional standard-cut washer required during installation

Frequently Asked Questions

What is the purpose of the Simpson BP 1-3 Bearing Plate?

The BP 1-3 is designed to provide a greater bearing surface than standard-cut washers and to distribute load at critical connections. It works by transferring concentrated compressive forces between two structural elements, making it a stronger and more reliable alternative to standard washers.

What bolt size is the BP 1-3 designed to accommodate?

The BP 1-3 features a 1-1/16" hole and is designed for use with a 1" diameter bolt. The BP series as a whole is sized for most common anchor bolt sizes ranging from 3/8" to 1".

How should the BP 1-3 be installed in shearwall applications?

For shearwall applications, position the edge of the plate washer within 1/2" of the sheathed edge of the track-bottom plate. No additional standard-cut washer is required. Tighten each anchor bolt with a nut and washer.

Is a corrosion-resistant coating available for the BP 1-3?

Yes. While the standard BP 1-3 has no coating, the BP series is available with a hot-dip galvanized (HDG) coating to protect the plate from corrosion when exposed to the elements, providing higher corrosion resistance for outdoor or exposed applications.
