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.
In the world of high-performance automotive engineering, precision is everything. This Auto Racing Products (ARP) flat washer is designed to provide a perfect fit for 12mm studs and bolts, ensuring that your critical engine and chassis components remain securely fastened. Whether you are performing a routine maintenance task or a full-scale engine build, using high-quality hardware is the best way to ensure long-term reliability.
Constructed from high-strength chromoly steel, this washer is designed to handle high torque loads without yielding. Its precise 12mm inner diameter ensures a snug fit, reducing lateral movement and vibration that can lead to fastener loosening over time. The 0.995-inch outer diameter is ideal for applications where space is at a premium but a secure clamping surface is still required. This washer is an excellent choice for cylinder head studs, main bearing caps, or any high-stress area of your engine. ARP is the industry leader in fastener technology, and this washer reflects their commitment to quality and performance. By upgrading your hardware, you are taking a proactive step toward protecting your engine's internal components from the stresses of high-performance driving. Ensure your build is ready for the track by sourcing your essential hardware from GGCRACING.
