The ARP 200-8447 hardened flat washers are precision-engineered fastener components designed for high-performance applications. These washers feature an M12 inner diameter (approximately .472 inches) with a .812-inch outer diameter and no chamfer design for maximum clamping surface area.

Key Features:

• M12 internal diameter for use with M12 bolts and studs
• .812-inch outer diameter provides optimal load distribution
• No chamfer design maximizes contact surface with the fastener head
• Manufactured from hardened steel for superior strength and durability
• Precision-machined to exact tolerances for consistent performance
• Ideal for racing, performance, and heavy-duty applications

ARP washers are heat-treated and finished to exacting standards, ensuring they can handle the extreme loads encountered in motorsports and high-performance builds. The no-chamfer design is specifically engineered for applications where maximum surface contact is required between the washer and fastener head.
