Wheel Locks
The wheel locks in this category typically replace one standard nut or bolt per wheel, so the wheel can only be removed with the matching key adapter. They are for you if you want to protect expensive wheels against theft.
How wheel locks work
A wheel lock has a special pattern in the head that only fits a supplied key adapter, so the wheel cannot be loosened with ordinary tools. You choose between locking nuts for cars with wheel studs on the hub and locking bolts for hubs with threaded holes. If your car currently uses standard lug nuts, you need the nut type. If it uses lug bolts, choose locking bolts. In this category you will find lock sets from e.g. McGard, Rays and Wheel Mate.
How to choose the right wheel lock
The lock must fit both car and wheel exactly, and several dimensions must match the nuts or bolts you already have:
- Thread – e.g. M12x1.25, M14x1.5 or imperial sizes such as 1/2-20.
- Seat – conical seat or ball seat must match the wheel's holes. The wrong seat can cause the wheel to come loose.
- Shank length on locking bolts – the right length depends on the wheel thickness and any wheel spacers.
- Hex size and diameter – e.g. 17 or 19 mm. Narrow holes in the wheel require that both the lock and the key adapter can fit down into the hole.
Fitting and maintenance
Tighten the locks with a torque wrench to the car's recommended torque, preferably using hand tools. An impact wrench can damage the pattern in the head and the key adapter. Typically re-torque after the first few kilometres. Keep the key adapter in a fixed place in the car. Note down the key code if the set has one, so you can order a new adapter if you lose it.
Frequently asked questions
How many wheel locks do I need per wheel?
Typically one per wheel, so a set of four locks covers four wheels. The rest of the wheel is fitted with standard nuts or bolts with the same thread and seat as the lock.
Can I use ball-seat locking bolts on wheels with a conical seat?
No. The seat must match the wheel's holes, otherwise the lock will not get the correct contact surface, and the wheel can come loose. Check the wheel manufacturer's specification or your current bolts before you order.
What do I do if I lose the key adapter?
If the set has a key code, you can often order a new adapter through the manufacturer. Without a code, removing the locks typically requires a workshop with special tools, and this can damage them.
