5" x 5" Square Plate Washer with 3/4" Diameter Hole

The 5" x 5" x 3/4" Square Plate Washer is an extra-heavy-duty bearing plate designed to provide an expansive surface area for superior load distribution in timber and concrete construction. Typically used with 3/4" anchor bolts or threaded rods, it effectively prevents fastener pull-through and reduces the risk of wood splitting or cracking in critical structural connections.

Technical Specifications

• Dimensions: 5 inches length x 5 inches width.
• Thickness: 3/8 inch (0.375"), providing high resistance to bending under extreme tension.
• Hole Diameter: 13/16 inch (nominally for 3/4" diameter bolts or rods).
• Material: Often manufactured from low-carbon steel for structural applications.
• Weight: Approximately 2.6 to 2.85 lbs per plate, depending on exact material density.

Key Features and Performance

• Enhanced Load Distribution: Its large 25-square-inch footprint distributes clamping force over a much wider area than standard round washers, which is essential for seismic and high-wind applications.
• Friction & Alignment: The square profile develops significantly more friction against wood surfaces, preventing rotation and maintaining precise alignment under heavy stress.
