Description
Constructed from 1045 carbon steel, they are heat-treated to 10.9 grade hardness. The unique 18-point acorn design offers three times greater contact area compared to traditional 6-point lugs, improving torque distribution and reducing the risk of stripping or rounding corners. They also feature a Neoshield coating for a durable finish.
