TheSimpson WASHER1?1/4?HDG is a heavy-duty flat washer designed to distribute load over a larger surface area when used with 1?1/4? bolts or threaded rods. Its hot-dip galvanized finish provides enhanced corrosion resistance, making it a reliable choice for outdoor, exposed, or treated lumber installations.

Key Features

• Compatible with 1?1/4? diameter bolts and threaded rods.
• Hot-dip galvanized (HDG) coating for excellent rust and corrosion protection.
• Heavy-duty steel construction resists bending and ensures even load distribution.

Applications

• Anchor bolt assemblies in concrete, wood, or steel structures.
• Used in foundation anchoring, post bases, framing connections, and heavy-duty structural joints.
• Ideal for outdoor or moisture-exposed environments including treated wood installations.

Installation

1. Position the washer between the nut and the mounting surface.
2. Tighten the nut to apply even clamping force through the washer.
3. Use with HDG-grade hardware for consistent corrosion resistance.
