Here's one >>

Using a wrench like that pictured, it screws right in, without need for double nutting. Also note: the un-threaded portion of the stud is a "stop". This prevents penetrating too far into the hub.

They come in "lengths", so getting the length right is important! To short: you'll have inadequate "stud to nut" thread contact. In most cases "overlength" is used with open ended lugs. In my case I wanted to use Porsche aluminum lugs (Porsche uses these on all their street cars, even turbos. Real race cars get steel). Being closed ended, I couldn't use overlength because the nut bottomed on the stud, before it contacted the wheel! Vendors include H&R (a disaster, their 40mm stud is actually 50mm, hence the bottoming incident) 2Bennett and Upgrade Motors in SoCal (pictured). The TT uses 14 x 1.50, diameter and pitch.<ul><li><a href="http://www.upgrademotoring.com/wheels/whl_acc.htm">Upgrade Motors</a></li></ul>
