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.
The Auto Racing Products (ARP) Chamfered Flat Washer is a specialized component designed for precision assemblies where fitment and clearance are critical. Featuring a 3/8 inch ID and 5/8 inch OD, this washer is crafted from high-strength chromoly steel, making it significantly more durable than standard hardware store alternatives. The chamfered edge allows for a flush fit against radiused surfaces, preventing binding and ensuring consistent torque readings.
In high-performance engine building, the smallest details can have the biggest impact. These washers are specifically designed to provide a stable base for bolts in tight or recessed areas. The chromoly steel construction ensures that the washer will not crush or deform under high pressure, maintaining the integrity of your fastener assembly. The black oxide finish provides a clean look and added resistance to rust and corrosion. Whether you are building a race engine, a custom transmission setup, or a high-performance suspension, these washers are an essential part of your hardware kit. Trust in the quality of ARP to provide the components that keep your vehicle performing at its peak. Browse our extensive selection of racing fasteners and engine components today at GGCRACING.
