ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
When every detail counts in your engine build, use Auto Racing Products (ARP) 7/16 ID x .660 OD chamfered flat washers. These premium fasteners are manufactured from high-strength chromoly steel to handle extreme clamping forces without deformation. The black oxide finish provides excellent corrosion resistance while maintaining a professional, clean look for your engine bay.
These washers are specifically designed to provide a uniform load distribution, which is critical for maintaining consistent torque values on high-stress bolts. The chamfered edge ensures that the washer seats perfectly against the bolt head radius, preventing binding and ensuring the fastener stays tight under vibration and heat. Whether you are performing a head gasket swap or a full engine rebuild, these ARP washers offer the reliability required for racing applications. Experience superior quality and performance with every component from GGCRACING.
