It is important that you know exactly, the following information to ensure you order the correct wheel nuts or wheel bolts, as wheels nuts / bolts are sold as per these specifications and are non-returnable / sold as a custom order.


HEX The main HEX sizes or wheel nut / wheel bolt head sizes available are: 17mm, 19mm and 21mm. Not all HEX sizes are available in all thread types. It is worthwhile finding out what your current hex size is so that your new wheel nuts or wheel bolts will be compatible in size with the sockets, spanners which are supplied with your cars spare wheel, thus ensuring that you can remove them with your existing tools in the event of a flat tyre at the side of the road.

We offer M12x1.25, M12x1.5, M12x1.75, M14x1.5, M14x2 and 1/2UNF. These thread types cover over 90% of cars available in the UK and Ireland, if you are unable to find out what type of thread type you need please give us a call and we can recommend what is the standard for you model of car. You can also purchase a Thread Pitch Guide which will help you determine what thread type your wheel nuts or wheel bolts are

If you are simply replacing your existing bolts with new ones please measure accurately the thread length on your existing bolt to ensure you order the correct replacement ones. If you need longer wheel bolts than normal please measure the total bolt length you require accurately. We offer a wide range of bolt thread lengths from 19mm, up to 73mm. Note: Not all these thread lengths are available in every hex and thread type combination, you can use our Wheel Nuts & Bolts Finder to see what is available in your specifications.


There are three main wheel nut / wheel bolt seating types, different companies / suppliers sometimes refer to them buy different names, but in essence there are 3 main ones:

60 Degree / Taper / Cone

This is the most popular wheel nut or bolt seating type for aftermarket wheels.

Radius Seat / Ball Seat / Round Seat

Popular seating type for OE (Original Equipment) wheels, or aftermarket wheels which are designed to use OE bolts / nuts, for example popular vehicles that use Radius seat are: VW, Audi, Seat, Mercedes, Skoda, Porsche etc.

Flat Seat

You will find flat seating Bolts are popular on Citroen, Peugeot and flat seating Nuts are popular on Toyota, Lexus and Land Rover vehicles fitted with OE (Original Equipment) wheels or aftermarket wheels which are designed to use OE bolts / nuts, otherwise the wheels would be designed to use 60’ taper nuts or bolts.

From the examples above you can see these different nut / bolt seating types. The correct nut / bolt seating type is required to ensure that the new nut or bolt seats correctly in your alloy wheel. Note: Most wheel nuts & bolts are available in the same seating types, but may not be available in the same thread types.

It is not recommended to use the wrong nut or bolt seating type, as such PerfomrnaceAlloys.com takes no responsibility for this… it’s up to You the customer to always check you are using the correct nut or bolt. Do not compromise on Safety… if you are unsure ask and expert!


In the diagram below you will see the three main bolt seating types. From this diagram you will be able to compare your original wheel nuts or bolts to find out what type of seating you have, as well as how to measure your thread length if you require a bolt.

The diagram depicts bolts as an example; nuts will also have similar seating, and if a nut height is listed this is the total height of the wheel nut.


We also have a wide range of special slimline, turner nuts and bolts. These are used when there is not enough space in the bolt hole to fit a standard wheel nut or bolt and or to fit a socket to tighten or remove, in this case Turner or Slimline nuts are used. Turner wheel nuts or bolts require a key which is inserted into the wheel bolt head in order to remove or tighten them. There are many different types of drive for these turner nuts, at performance alloys we use the spline / star drive option as per the pictures listed.


We currently stock both turner bolts and turner nuts in an overall diameter of 20mm or 23mm.


Delivery is by courier normally DHL, TNT, UPS etc. unfortunately due to the nature of this product, once any wheel nuts or wheel bolts have been ordered and supplied correctly as per the specifications listed on our website we cannot accept any nuts or bolts back for return.

All wheels nuts and bolts are a custom order to your specifications. As such it is very important that you ensure you order the correct type of nuts or bolts for your car at the start.
