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.
Vibration is the enemy of any high-performance engine. The ARP M10 x 1.25 Locking Flange Nut Kit is specifically engineered to stay tight, even under the most punishing conditions. This 10-pack provides the perfect solution for securing exhaust manifolds, turbo components, or any high-heat, high-vibration area of your engine.
Using standard nuts in critical areas can lead to leaks, blown gaskets, and potential engine damage. ARP’s locking flange nuts provide a robust, reliable alternative that ensures your hard work stays secure. These nuts are designed to be reused without losing their locking effectiveness, making them a smart investment for any serious mechanic or racer. The M10 x 1.25 thread pitch is a common size for many modern import and domestic performance engines, offering a direct upgrade over factory hardware. Ensure your engine components remain locked in place with the industry-leading quality of ARP. For expert advice and premium engine hardware, look no further than GGCRACING.
