Description: This kit of four plastic caps is for use with lockable lug nut kit. 19, matt gray. The lock pattern is located against the middle on the lockable bolts and is therefore difficult to reach with a screwdriver, for example. The top of the lockable bolt rotates and is therefore very difficult to loosen without the right wrench. A solid connection between wrench and bolt facilitates installation and removal, and generally eliminates the risk of crooked tightening.
