The nuts are made from high-strength steel, ensuring they can withstand the rigors of high-rpm engine operation. They have a 12-point design, which provides superior grip and torque transfer to the rocker arm, reducing the risk of loosening or failure under extreme conditions.
The nuts have a 31.8mm thread size, making them suitable for use with a wide range of rocker arms and engines.
