ARP 200-8722 1/2" ID 1.30" OD Black Oxide Washers

ARP 200-8722 high-quality black oxide coated washers feature a 1/2 inch inner diameter and 1.30 inch outer diameter, designed for use with ARP fastener systems and high-performance applications. These precision-manufactured washers provide proper load distribution and help prevent fastener embedment under high clamping loads.

Key Features:

• 1/2 inch inner diameter for use with 1/2" bolts and studs
• 1.30 inch outer diameter provides excellent load distribution
• Black oxide finish for corrosion resistance and professional appearance
• Precision machined for consistent thickness and flatness
• Ideal for engine builds, suspension assemblies, and high-stress applications
• Compatible with ARP Ultra-Torque fastener assembly lubricant

ARP washers are manufactured to exacting standards to ensure proper seating and load distribution in critical fastening applications. The larger outer diameter helps spread clamping force over a wider area, reducing the risk of material deformation in softer metals like aluminum.
