Features
This wheel nut set includes security lock nuts, which are highly effective in preventing wheel theft, and lug nuts, which require a special socket for installation and removal, and features an enhanced locking function and the original NISMO logo. The security lock nuts’ numerous key patterns and special shape provide a high level of security.

In addition, since the washer on the mounting surface is free, it can be tightened without damaging the wheel seat until just before torque is applied, so the wheel will not be damaged.

Note:

• Can only be used on wheels with tapered mounting surfaces. Cannot be used on light vehicles or wheels with flat mounting surfaces.
• Do not use on vehicles with long hub bolts or in combination with commercially available wheel spacers. Doing so may cause the bolts to come loose and lead to an accident.
• Even if you use the included wheel nut adapter, the clearance between the hole and the wheel nut adapter is small, so depending on how you handle it, it may cause scratches or peeling on the painted surface. Be careful not to interfere with the wheel. Also, refrain from using an impact wrench.
• These nuts are not designed for circuit driving, so if you are driving on a circuit, please use nuts suitable for circuit driving, such as NISMO racing nuts.
• If you lose the dedicated socket, please contact McGard.
