Truck and Automotive Market applications

Automotive warranty cost attribute 70% to fastener failures, most from over-tightening. Since 2/3 of all labor is assembling, over tightening happens. The Van Cor Threads can not be over-tightened and the quick connection aspects will eliminate some electric screw drivers. These threads can be designed to connect in a half a turn - a twist of the wrist.

The Van Cor Threaded parts can be molded at the same cost as most threads. Machining will be two to three times more expensive. Another capability of the partial use of concentirc threads is that they are build into the components. An example for attaching four corners would be the threads are on the corners and a single screw keeps is from backing out. For those who understand these threads, that single screw would be more for show.
