Spline & Tuner Lug Nuts
Spline Drive Tuner Lug Nuts
Spline drive lug nuts use a narrow, splined body that fits the small lug holes on many aftermarket and tuner wheels, and install with the included spline key. Stocked in 12x1.25, 12x1.5, 12x1.75, 14x1.5, 14x2, 1/2", 7/16", 9/16".
Shop by thread size: 12x1.5, 12x1.25, 12x1.75, 14x1.5, 14x2, 7/16", 1/2" and 9/16".
Choosing spline drive lug nuts
Pick spline drive when your aftermarket wheels have lug holes too narrow for a standard hex nut. The splined design also adds a basic layer of theft deterrence, since removal needs the matching key. Available closed and open end, in chrome, black and colored finishes.
Common questions
Do spline lug nuts come with the key? Yes, our spline sets include the matching spline drive key. Keep it with your spare tire kit, since a standard socket will not remove them.
Are spline drive nuts secure against theft? They deter casual theft because they need the key, but a determined thief with an extractor can still remove them. For higher security, pair them with a locking set.
Will they fit factory wheels? Usually yes with the correct seat, but they are designed for aftermarket wheels with narrow lug holes. Factory wheels are often better served by OEM-style nuts.
Torque specs are on our torque reference chart, and our wheel fitment guide covers how to confirm your thread size.
