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.
Upgrade your hardware with Auto Racing Products (ARP) 5/16 ID flat washers. Designed for the serious builder, these washers provide the necessary support to ensure your fasteners hold tight under the most demanding conditions. With a 0.625-inch outer diameter and a durable 0.12-inch thickness, they are perfectly sized for a wide range of automotive applications, including accessory brackets, valve covers, and interior trim.
Using improper or standard hardware store washers can lead to uneven clamping force and potential hardware failure. ARP washers are specifically manufactured to meet the rigorous standards of the racing industry. The chamfered design ensures that the washer sits flat against the fastener, while the stainless steel construction resists corrosion even in harsh under-hood environments. These washers are an easy and effective way to improve the reliability and aesthetic of your engine bay. Equip your vehicle with the best components available by shopping at GGCRACING.
