Description

The Gorilla Automotive 21188BC Small Diameter Spline Acorn Lug Nuts are designed to set the industry standard for quality and durability in wheel fasteners. These lug nuts come in a sleek black finish and are engineered with a small diameter spline acorn style. They feature a closed-end design and a conical seat type, ensuring a secure fit for many applications. Constructed from heat-treated metal for enhanced strength and longevity, these lug nuts boast precise specifications: an overall length of 1.36 inches, an outside diameter of 20 MM, and a 1/2-20 thread pitch. This combination of features makes them a reliable choice for attaching wheels, providing an upgrade over inferior fasteners. The manufacturer also states that fitment cannot be guaranteed without vehicle selection, advising customers to confirm compatibility for their specific vehicle options.
