The Dorman 9/16-18 Serrated Wheel Stud is a direct replacement lug stud designed to restore safe, secure wheel mounting when replacing damaged or worn studs. Manufactured from durable steel and tested to demanding automotive industry standards, it’s built to meet SAE requirements for strength, longevity, and safe service.
This serrated stud design supports secure hub engagement, and each stud is proof-load tensile tested to help ensure dependable strength. Extensive salt spray testing also helps improve corrosion resistance for durability against rust over time. This specific stud features left-hand (counterclockwise) thread direction, making it important for proper fitment on applications that require reverse-thread wheel hardware.
