Which wheel nuts we have
- 60° conical nuts. The most common type – for most steel and alloy wheels.
- Ball seat nuts. For rims with a ball seat, e.g. some Honda wheels.
- Flat seat nuts with a washer. For factory alloy wheels of e.g. Toyota, Lexus and Mitsubishi.
- Nuts with an extended shank. For original alloy wheels with holes larger than 16 mm and for rims with deep seats.
- Locking nuts. A set with a uniquely patterned key – against wheel theft.
Closed or open-ended?
A closed nut (capped) covers the end of the stud – protecting the thread from water, salt and rust. A good choice if the stud does not protrude too far.
An open-ended nut (open) lets the stud pass through. It is used with longer studs, e.g. after fitting spacers or with thin rims.
A closed nut on a stud that is too long will bottom out on its end before clamping the rim – the wheel will be loose despite a “tightened” nut.
How to choose wheel nuts
- 1. Stud thread. Usually M12×1.5 or M12×1.25, in larger cars M14×1.5. The thread is fixed for the car, regardless of the rim.
- 2. Seat in the rim. Cone, ball or a flat surface with a washer – it must match the nut.
- 3. Hole diameter in the rim. Some factory alloys have a wider hole and need a nut with a sleeve that fits and centres in it.
- 4. Wrench size and outer diameter. Usually 19 or 21 mm. Narrow holes need a nut with a smaller diameter.
Switching from factory rims to others?
The most common mistake: when switching from original Toyota rims with flat-seat nuts to aftermarket rims, the old nuts stay on. New rims usually have a conical seat, so conical nuts are needed.
The same applies the other way round – when fitting original rims, go back to the original nuts. We check this at every wheel change.

Frequently asked questions
A short guide to what customers ask most often.
- How much do wheel nuts cost?It depends on the type and quantity. Call, tell us your car and rim type – we will say what we have on site and how much it costs.
- Do conical nuts fit rims with a flat seat?No. The nut must have the same shape as the seat in the rim, otherwise the rim is not clamped correctly.
- How do I check the stud thread?Check your model in our car finder or bring one nut – we will match it on site.
- Do nuts need replacing with new rims?Often yes – it depends on the seat in the new rim and the thickness of its flange. We check this before fitting.
- A stud is broken – what now?The stud must be replaced. It is a mechanical repair – our mechanic will do it on site.
