Understanding Spline Key Lug Nuts

When I first came across spline key lug nuts, I was intrigued by their unique design. Unlike traditional lug nuts, spline key lug nuts feature a splined exterior that requires a specific key for installation and removal. This design not only enhances security but also adds a sleek look to my wheels.
