Abstract: A device is disclosed herein for aiding in properly connecting the threaded segment of one object, for example a spark plug, to a complementary threaded segment of a second object, for example an engine block including a complementary threaded hole. This device is designed so as to be capable of applying sufficient torque to the first object to loosely connect its threaded segment to the threaded segment of the second object in a properly threaded fashion. On the other hand, the device is designed so as not to be able to apply sufficient torque to the first object to connect together the threaded segments in a way which would strip or otherwise damage the threads. In this way, once the two objects are loosely connected together in a properly threaded fashion, a second device, for example a standard socket wrench, can be utilized for tightening the two objects without fear of damaging their threads.
