Drilling need with the help of the conductor, which will help to make a hole exactly in the center. Be sure to save necessary wall thickness of the recoverable items.
After the hole is ready, insert the extractor, which neatly screw inside. Remember that this device has a left-hand thread, so it will be screwed in the opposite direction. After some time he will finish the spin and start to go out with a stuck pin.
Try to drill a fallen item. Be very careful and patient. Remember, however, that if the probability of getting small metal shavings inside the important components and assemblies, then abandon this method. Also try using a drill with left-hand thread, which drill into the surface at low speed. Often the thread starts to wane due to the left stroke drills and damaged the pin easily comes out.
If the surface and space allow the use of welding, the weld to the protruding end of the stud nut. After that, pick up a wrench of the desired diameter and begin to Unscrew the nut that pulled out behind him and the rest of the details.
