What is A Locking Wheel Nut?

By David Sholicar

Tyres and alloy wheels are expensive items and that makes them attractive to thieves. In recent years, therefore, it’s become commonplace to fit cars with locking wheel nuts to make it harder to steal the wheels.

Locking Wheel Nut

Locking wheel nuts come in a set of four, together with the appropriate ‘key’ to allow them to be undone. You only need to fit one locking nut to each wheel, leaving the other standard nuts in place. The key needs to be kept in the car should you need to change a wheel, but make sure that you keep it out of sight in the boot or the glove compartment. If you have to change a wheel yourself, always undo the lock nut first and replace it last.
There are three types of locking wheel nut in general use today. The first and most common type has a keyed head to the nut. You slot the key into this, the other end of the key has a standard hex head that fits a wheel brace so that you can undo the nut in the normal way.

The second type of nut has a rotating collar that spins around the nut, making attempts at forced removal without the proper key more difficult. The final type is the ‘shear head’ these are usually used where the wheel has bolts rather than nuts and they are often fitted on Citroen and Peugeot models. On this type, the head of the bolt is designed to shear off if a tool other than the proper key is used to attempt to remove it.

Most new cars now come with locking wheel nuts or bolts as standard. As a result, theft of wheels as an opportunist crime is now relatively rare in the UK unless you have a particularly unusual or valuable car and wheels. While locking nuts are a deterrent, if criminals really want your wheels, they will find a way to take them, even if it means lifting the whole car. You shouldn’t, therefore, neglect basic vehicle security, parking your car in well-lit areas or keeping it in a garage, for example.

If you lose or damage your locking wheel nut key, then removing your wheels is going to be a problem. Fortunately, at Protyre, our tyre professionals can help, it’s always better to get someone with experience to do the job in these circumstances rather than attempting it yourself.
