ARP Chrome Moly Washer

ARP Chrome Moly Washers are high-strength hardened flat washers made for performance and racing fasteners. They are also sold as chrome moly hardened washers or performance washers. They give a smooth, flat bearing surface under bolt heads and nuts, which helps spread clamping load and protects the mating surface.

• Made from chrome moly alloy steel for high strength and durability
• Hardened to resist deformation and crushing under high clamping loads
• Designed to pair with ARP bolts, studs and nuts in demanding engine and drivetrain assemblies
• Precision-manufactured for consistent thickness and a flat seating surface
• Available in multiple styles and finishes to suit different ARP fastener applications
