Description

The Gorilla Automotive K5CS-12150BGR is a set of 20 small diameter spline acorn lug nuts designed to provide a secure fit for most aftermarket wheels. These lug nuts feature a closed-end design, a conical seat type, and a M12-1.50 thread pitch, ensuring compatibility with a wide range of wheel applications. The black finish offers a sleek aesthetic, while the heat-treated construction enhances durability and longevity. Included with this kit is a specialized 1921SD-KEY dual hex tool, which accommodates both 3/4" (19mm) and 13/16" (21mm) hex sizes, simplifying installation and removal. The overall length of each lug nut is 1.36 inches, and their outside diameter is 20 MM, making them suitable for wheels with tuner-style or small diameter openings. It is recommended to verify fitment with your specific wheel application before purchase. Gorilla Automotive warrants its products to be free from defects in materials or workmanship for a period of one year from the date of delivery.
