Gorilla Automotive K5TS-00012BGR Small Diameter Spline Duplex Lug Nuts - 1/2-20 Black 20-Pack

The Gorilla Automotive K5TS-00012BGR Small Diameter Spline Duplex Lug Nuts deliver enhanced wheel security with their unique dual-drive design. These professional-grade lug nuts feature a spline drive system that requires a special key tool for installation and removal, providing superior theft deterrence compared to standard lug nuts.

Key Features:

• Thread size: 1/2-20 RH (right-hand thread)
• Dual hex socket sizes: 13/16" and 7/8" for duplex functionality
• Small diameter spline drive design for aftermarket wheel compatibility
• Heat-treated steel construction for improved finish and long-lasting durability
• Black finish complements dark wheels and provides corrosion resistance
• Complete kit includes 20 lug nuts plus one spline key tool (1378SD-KEY)

These lug nuts are specifically engineered for aftermarket wheels and may not be compatible with original equipment factory wheels. The spline drive pattern requires the included key tool for installation, making unauthorized wheel removal significantly more difficult. Ideal for custom wheel setups where security and appearance are priorities.
