Lug Nuts and Locks

Common questions

What lug nuts do I need

The thread pitch your car uses, the seat your wheel uses, and a drive that clears the lug hole. Save your car and these listings filter to the right thread. The wheel page names the seat, which on almost every aftermarket wheel is conical. Narrow lug hole? Pick a spline drive or a tuner nut and keep the key in the car, not on a bench where you'll forget it.

Are aluminum lug nuts safe

On a street car torqued by hand, yes. Aluminum is softer than steel, so an impact gun rounds the corners and too much torque strips the thread. They also corrode against a steel stud in a salt state if you never take them off. Steel or chromoly is the answer for a car that's seeing track days and tire shop guns.

Conical or ball seat

It's the shape of the surface doing the clamping. A conical seat is a sixty degree cone and it's what nearly every aftermarket wheel is cut for. A ball seat is a rounded radius, and that's what a lot of Honda and Toyota factory wheels use, along with the German ones. Mixing them puts the nut on a ring instead of a surface, and it works loose.

Do I need wheel locks

If the car sleeps on the street, yes. A lock swaps one nut per wheel for one that wants a keyed socket, which stops the easy theft cold. It won't stop somebody determined. Keep the key in the car, write the code from the box down somewhere, and tell the tire shop where the key is before they start.
