Fastener Flatwasher

Fastener Flatwasher

This 1-inch SAE flat washer is a standard hardware component used throughout various systems on concrete mixer trucks, including drum mounts, chute pivots, and structural brackets. Manufactured to Society of Automotive Engineers (SAE) specifications, it features a smaller outer diameter and thinner gauge than USS washers, making it ideal for tight-clearance applications. It provides a smooth bearing surface that distributes the clamping force of a 1-inch bolt or screw, preventing pull-through and protecting the underlying equipment surfaces from damage.

Key Features

• 1-inch SAE standard sizing for tight-clearance fastener applications
• Zinc-plated steel construction for enhanced corrosion and rust resistance
• Distributes load evenly to prevent fastener pull-through and surface damage
• Smaller outer diameter (2-inch) compared to USS standard washers
