Gorilla Automotive K5COS-14150GR Small Diameter Spline Drive Duplex Lug Nuts 14x1.5 Thread 20-Pack

The Gorilla Automotive K5COS-14150GR is a complete set of 20 small diameter spline drive duplex lug nuts designed for aftermarket wheels. These specialized lug nuts feature an open-end design with a 14mm x 1.5 thread pitch, making them compatible with many import and domestic vehicles using metric wheel studs.

Key Features:

• Small diameter design fits wheels with limited lug hole clearance
• Duplex spline drive system requires 13/16" and 7/8" dual hex key for enhanced security
• Heat-treated zinc finish improves corrosion resistance and durability
• Open-end design accommodates extended wheel studs
• 20-piece kit includes one 1378SD spline drive key tool

These lug nuts are specifically engineered for most aftermarket wheels and may not be compatible with original equipment factory wheels. The spline drive system provides better engagement and reduces the risk of rounding compared to standard hex lugs, while the small diameter body ensures proper fitment in wheels with tight lug seat pockets.
