How Do the Audi S4 Lock Bolts Work?

This type of Audi B9 S4 lug bolts refers to the bolts with spline grooves on the head and require a special key. When the key with hex socket inserts sets the bolt inside, the spline drive key fits around the outside grooves of the bolt. This allows you to install/remove the locking bolts. The requirement of a unique tool reduces the risk of stripping the lug bolt and prevent the wheel from theft. Like the common aftermarket wheel bolts, these are widely found on aftermarket wheel applications. Furthermore, they add security for your wheels. Meanwhile, their smaller head diameter makes them lighter. This makes them popular among many performance-conscious track enthusiasts.
