QT-121-4C-BK QTEQ Smart Wheel Nut - Recessed Type (Black - 4 pcs)

Precision machined out of 7075-T6 Aluminum , the QTEQ Smart Wheel Nut is better due to the design. 

The Recessed Type Wheel Nut is designed to be used on the front wheels of 2WD Vehicles with an M4 Axle. The Wheel nut has a Lip Machined on to the back side of the nut which acts as a crush washer on the inner diameter bearing race which allows for tighter fastening of the front wheels without binding the bearings. 

In order to further increase the performance of the nut, QTEQ's proprietary nylon locking inserts are used. These inserts have been developed over the years and last longer and hold tighter than other ones available in the market.

Lastly, we have the design. Why the funny tool?  Well, not only does it look cool, but it serves a function as well. The shape of the wheel nut and tool allow them to interlock and not fall out of the socket when installing them in the car. Not a must have, but a certain convenience that makes life a lot easier when working on your car.
