Heavy-Duty Chromoly Flat Washers

When building a high-performance engine or chassis, standard hardware simply won't cut it. These Auto Racing Products 1/2 ID x 7/8 OD black chromoly washers are engineered for maximum load-bearing capacity. Crafted from high-strength chromoly steel, these washers are designed to resist crushing and deformation, even when torqued to extreme specifications.

Key Features and Specifications

  • Dimensions: 0.5 inch Inner Diameter x 0.875 inch Outer Diameter.
  • Thickness: 0.12 inch heavy-duty profile.
  • Material: High-strength chromoly steel.
  • Finish: Black oxide coating for superior corrosion protection.
  • Quantity: Sold as a 2-pack.

These washers are a must-have for critical mounting points, such as suspension components, engine mounts, and transmission bolts. The extra thickness provides a larger contact patch, which effectively distributes clamping force and protects the surface of your components from galling or damage. By using professional-grade hardware like these chromoly washers, you ensure that your fasteners remain tight and secure under the intense vibration and heat cycles of competitive racing. Don't compromise your build with inferior hardware—trust the durability of Auto Racing Products available at GGCRACING.
