TPi nuts and locks are made to fit both your vehicle and your wheels. Things you need to check are: that you’re buying the correct thread diameter and pitch for your car. Also that your wheels have tapered seated (cone shaped) bolt pockets. Buy alloy nuts singly, locks in a pack of 4, or why not buy our pre-packs of 16 nuts and 4 locks with key included. If you’ve changed your wheels from the standard factory ones, then there’s every possibility the nuts or bolts will need to be different – and the same applies to the locks. If your bolt pockets are smaller than standard and too small to accept a standard socket, then click here for our small diameter (SD) nuts and tuner bolts.
