Product Overview
The 1/2-20 Black Spline Lug Nuts are designed for vehicles requiring a 1/2-inch thread pattern and offer both security and style. Their spline drive design provides a slimmer profile for aftermarket wheels with narrower lug holes, while also requiring a special key for installation and removal—making them more secure than standard hex lugs.
The black finish gives them a sleek, aggressive look that pairs perfectly with dark or custom wheel setups. Their closed-end construction helps prevent dirt, moisture, and road debris from entering the threads, extending the life of both the lug and the stud.
Built for strength and long-lasting performance, these lug nuts are an excellent choice for cars, trucks, and SUVs running a 1/2-20 stud pattern.
