The Simpson LBP 1/2Z Light Bearing Plate from Simpson is a structural connector engineered to provide a greater bearing surface than standard-cut washers and help distribute load at critical connections. Sized specifically for 1/2-in. diameter mudsill anchor bolts, this compact 2 in. x 2 in. plate works by transferring concentrated compressive forces between two structural elements - delivering reliable performance where it matters most. Its ZMAX galvanized finish makes it a dependable choice for exterior and treated-wood applications where corrosion resistance is essential.

Key Features

• Greater bearing surface than standard-cut washers - spreads compressive load more effectively at critical structural connections, reducing stress concentration at the anchor bolt point
• Designed and sized for 1/2-in. diameter mudsill anchor bolts - ensures a proper, code-conscious fit without modification or guesswork at the connection point
• 2 in. x 2 in. footprint with 9/64 in. thickness - a low-profile plate that delivers meaningful load distribution without adding bulk to the assembly
• ZMAX galvanized finish - offers extra corrosion resistance beyond standard galvanized coatings, making this bearing plate well suited for exterior installations and direct contact with treated lumber

Why This Product

• A direct upgrade over standard washers - the LBP 1/2Z replaces ordinary cut washers with a purpose-built bearing plate that provides a greater surface area for load distribution, improving connection integrity at mudsill anchor bolt locations
• Built for treated-wood and exterior conditions - the ZMAX galvanization provides extra corrosion resistance specifically suited for the harsh chemical environment of pressure-treated lumber and outdoor exposure
• Engineered for a specific job, not a generic fit - designed and sized exclusively for 1/2-in. diameter anchor bolts, this plate removes the uncertainty of selecting a general-purpose washer for a structural application
• Trusted Simpson engineering for a foundational connection - the mudsill-to-foundation connection is one of the most critical load paths in a structure, and this plate is purpose-built to handle the compressive force transfer at that point reliably
