The Simpson LBPS 1/2Z ZMAX Galvanized Slotted Bearing Plate is a 3 in. x 3 in. slotted anchor bolt washer plate engineered by Simpson to provide a greater bearing surface than standard cut washers, strengthening and distributing load at critical connections. Designed primarily for use on foundation anchor bolts in sill plate applications, this slotted bearing plate delivers the adjustability and corrosion resistance that framing crews need when working on 2x4 and 2x6 wall assemblies in both exterior and treated-wood environments.

Key Features

• Slotted hole design - allows for on-site adjustability to account for anchor bolts that are not centered in the sill plate, reducing the need for rework and keeping installation moving.
• Increased flexibility for code compliance - meets the latest code requirements for 2x4 and 2x6 walls, giving builders a single solution that works across the most common residential and light commercial framing applications.
• 3 in. x 3 in. bearing surface - covers significantly more area than a standard cut washer, spreading the load more effectively at foundation anchor bolt connections for a stronger, more secure tie.
• ZMAX galvanized coating - provides extra corrosion resistance for exterior and treated-wood applications where standard galvanized finishes may fall short, helping the plate hold up in demanding environments.
• 9/64 in. thickness with 1/2 in. bolt diameter compatibility - precisely sized to pair with standard 1/2 in. anchor bolts, ensuring a proper fit without guesswork on the jobsite.

Why This Product

• Built-in adjustability eliminates installation headaches - the slotted hole accommodates anchor bolts that are off-center in the sill plate, so crews can secure the connection without relocating hardware or modifying the plate.
• Superior load distribution where it matters most - by replacing standard cut washers at foundation anchor bolt locations, this bearing plate strengthens critical sill-to-foundation connections and reduces point stress on the framing.
• ZMAX protection for treated-wood and exterior use - the extra-heavy galvanized coating is specifically suited for contact with pressure-treated lumber and outdoor exposure, making it a dependable choice for conditions that would degrade lesser finishes.
• Code-ready for the most common wall assemblies - designed to meet current code requirements for 2x4 and 2x6 walls, this slotted sill plate washer simplifies compliance on residential and light commercial framing projects.

Frequently Asked Questions

What is the purpose of a slotted bearing plate compared to 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 these critical connections, making them especially effective at foundation anchor bolt locations in place of cut washers.

Why does the LBPS 1/2Z have a slotted hole instead of a round hole?

The slotted hole allows for adjustability to account for bolts that are not in the middle of the sill plate, providing on-site flexibility during installation without requiring repositioning of the anchor bolt.

What does ZMAX galvanization mean for this bearing plate?

ZMAX galvanization offers extra corrosion resistance for exterior and treated-wood applications, making the LBPS 1/2Z suitable for use in environments where standard galvanized finishes may not provide sufficient protection.

Which wall types is the LBPS 1/2Z designed to work with?

The LBPS 1/2Z offers increased flexibility while meeting the latest requirements of the code for 2x4 and 2x6 walls, making it a versatile choice for common residential and light commercial framing applications.
