9/16" CLOSED END (LONG) BULGE ACORN

The RHI lug nut kit is constructed from 1045 carbon steel and heat-treated to 10.9 grade hardness. It features a unique 18-point acorn lug design that offers three times greater contact area than traditional 6-point lugs. This design improves torque distribution and reduces the risk of stripping or rounding corners.

The lug nuts are finished with a proprietary Neoshield coating, a nanotechnology that fuses to the surface, virtually eliminating porosity and providing a smooth, shiny, and durable finish. This coating offers superior protection against rust and corrosion, exceeding 300+ hours in salt spray tests. The kit includes 16 lug nuts, 4 locking lug nuts, and 1 key, with a length of 1.90" and a thread size of 9/16" x 18.
