High-Strength Fasteners for Critical Applications

When building an engine, every fastener matters. These Auto Racing Products (ARP) flat washers are manufactured from high-strength chromoly steel, designed to handle the extreme clamping loads found in high-performance racing engines. With a 12mm inner diameter and 0.75-inch outer diameter, these washers are the perfect choice for securing cylinder heads, main caps, or custom brackets.

Engineered for Performance

  • Material: Premium chromoly steel for maximum tensile strength.
  • Finish: Black oxide coating provides excellent corrosion resistance and a professional look.
  • Dimensions: 12mm ID, 0.75 inch OD, 0.12 inch thickness.
  • Versatility: Ideal for high-vibration and high-heat environments.
  • Reliability: Prevents fastener galling and ensures even distribution of clamping force.

Don't settle for hardware-store washers that can deform under torque. ARP hardware is the industry standard for a reason, providing the peace of mind that your engine internals are secured properly. Whether you are performing a full rebuild or simple maintenance, these washers are a must-have for any serious mechanic. Get your high-performance hardware from GGCRACING.
