The Gorilla Automotive K5COS-12125GR is a complete 20-piece lug nut kit designed for aftermarket wheels requiring small diameter spline drive installation. These lug nuts feature a 12mm x 1.25mm thread pitch and come with an open-ended design to accommodate extended wheel studs. Each lug nut is finished in corrosion-resistant zinc plating for long-lasting protection against the elements.

Key Features:

• Small diameter spline drive design with open end configuration
• 12mm x 1.25mm thread pitch for precise fitment
• Heat-treated construction improves finish durability and strength
• Zinc-plated finish resists rust and corrosion
• Requires 3/4-inch or 13/16-inch spline key for installation (included)
