About Five Star Fabricating

Achieve superior load distribution and unparalleled material protection with the Five Star Fabricating Large Avex Style Aluminum Backup Washer. Specifically designed for applications requiring a wider footprint, this washer is crucial for preventing fastener pull-through and reinforcing softer or thinner materials in high-stress automotive and racing environments. Maximize the lifespan and stability of your assemblies.

Expanded Surface Area for Enhanced Support

This large-format backup washer is expertly manufactured from premium aluminum with a natural finish, offering an optimal balance of strength, lightweight properties, and corrosion resistance. Following Avex style specifications, it features a 0.188-inch inner diameter (3/16 inch) to accommodate standard fasteners, combined with a significantly larger 0.75-inch outer diameter. The 0.042-inch thickness provides robust reinforcement while maintaining a low profile, making it perfect for critical paneling and structural applications.

Distinct Advantages of Large Backup Washers

  • Maximized Load Spread: The generous outer diameter distributes clamping force over a much larger area, ideal for composite panels or thin sheet metal.
  • Prevents Material Damage: Significantly reduces the risk of dimpling, cracking, or tearing around the fastener hole.
  • Lightweight & Durable: Aluminum construction ensures minimal weight addition with maximum resistance to environmental factors.
  • Bulk 500-Piece Supply: Ensures you have an abundant quantity for extensive projects, professional use, or workshop inventory.

When your project demands exceptional fastener support and material integrity, especially with delicate or high-performance substrates, these large aluminum backup washers are the definitive choice. Their ability to provide a broad, stable base for your fasteners translates directly into more secure, longer-lasting assemblies. Invest in the superior protection that only Five Star Fabricating can provide.
