The Simpson LBP 5/8Z 2 in. x 2 in. ZMAX Galvanized Bearing Plate from Simpson is engineered to provide a greater bearing surface than standard-cut washers, making it a reliable choice for distributing loads at critical structural connections. By transferring concentrated compressive forces between two structural elements, this light bearing plate strengthens mudsill anchor bolt assemblies where point loads demand more than a conventional washer can deliver. Its ZMAX galvanized finish delivers extra corrosion resistance, keeping it well suited for exterior conditions and contact with treated wood.

Key Features

• Greater bearing surface than standard-cut washers - spreads load more effectively at critical connections, reducing the risk of localized stress concentrations in structural assemblies
• Sized for 5/8-in. diameter mudsill anchor bolts - designed specifically for this bolt size, ensuring a precise, secure fit without improvised modifications
• 2 in. x 2 in. footprint - provides a substantial contact area that a standard washer cannot match, supporting reliable load transfer between structural elements
• 9/64 in. thickness - offers meaningful rigidity for handling compressive forces while keeping the plate compact within the connection assembly
• ZMAX galvanized finish - provides extra corrosion resistance beyond standard galvanizing, making this plate a dependable option for exterior and treated-wood applications where moisture exposure is a concern

Why This Product

• Purpose-built for mudsill anchor bolt connections - unlike generic washers, this bearing plate is specifically designed and sized for 5/8-in. diameter anchor bolts, so it integrates cleanly into mudsill installations without guesswork
• Improved load distribution at high-stress connection points - by transferring concentrated compressive forces across a larger surface area, this plate helps protect the surrounding structural material from damage that undersized hardware can cause over time
• ZMAX coating for long-term performance in harsh environments - the ZMAX galvanized finish offers extra corrosion resistance that makes this plate suitable where standard coatings fall short, including exterior applications and assemblies involving treated lumber
• A direct upgrade over standard-cut washers - designed to replace conventional washers outright, this bearing plate delivers greater bearing area and more consistent performance with no additional hardware needed
