- 14mm x 1.5 thread size
- Kit contains 20 pieces
Spline nuts and seat matching
Spline lug nuts use a fluted collar that fits a matching spline bore in the wheel. Conical and ball seat nuts look similar but do not seat the same way, so a spline nut on a conical wheel can loosen or fail to clamp evenly. Identify the seat type on each wheel before buying a set.
Spline nuts often come with a dedicated drive socket, and a standard socket can round off the flutes. When you change to a spline set, replace any mismatched nuts on the same vehicle and keep the set together for rotations. Check the threads for damage before reuse.
- Use the matching spline drive socket
- Keep all nuts for one vehicle in a single set
- Check threads for burrs or corrosion before reinstalling
