Hi Jose, I am pleased to assist you. The Dorman (manufacturer) website does not specifically indicate that it is a Grade 10 bolt. In general, bolt grades are classified based on their tensile strength and yield strength ratio. Given its use in automotive applications like control arms, it is likely designed to meet specific durability standards, though not explicitly stated as Grade 10. The product description does mention that the bolts are made from high-quality materials, likely carbon steel, and are designed for durability and long service life.
