Product Details

ARP 200-8780 black oxide washers are precision-manufactured fastener components designed for high-performance engine and automotive applications. These washers feature a 7/16-inch inner diameter and .705-inch outer diameter, providing optimal load distribution and secure fastening for critical assemblies.

Key Specifications:

  • Inside Diameter: 7/16 inch (0.4375")
  • Outside Diameter: 0.705 inch
  • Black oxide finish for corrosion resistance
  • Manufactured from high-quality steel
  • Precision ground for flat, parallel surfaces
