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.
When you need heavy-duty fastening power, look no further than these ARP M12 x 1.50 x 25 hex bolts. Engineered for high-stress environments, these bolts provide the clamping force necessary to keep critical engine components and chassis parts securely in place. ARP is the industry leader in fastener technology, and these M12 bolts are built to meet the most demanding performance standards.
The black oxide finish provides a durable, professional look while offering excellent resistance to wear and environmental factors. These bolts are ideal for applications requiring a shorter 25mm length, such as mounting brackets, transmission components, or suspension parts. Because ARP uses high-grade materials and rigorous heat-treating processes, these bolts offer superior tensile strength compared to standard hardware store alternatives. You can trust that these fasteners will not stretch or loosen under heavy load, ensuring your vehicle remains safe and reliable on the track or the street. The precision-machined threads allow for smooth installation and accurate torque application, preventing damage to your components. Whether you are performing a full engine build or simple maintenance, using the right hardware is essential for long-term success.
