How Would You Remove a Broken Fastener with a Fluted

Question

Examlex · Accepted Answer

The Answer is First, make a centerpunch mark precisely in the center of the fastener.
Then, drill a hole of a precise size into the broken fastener. The drilled hole should go all the way through the bottom of the fastener. The first hole should be drilled with a small drill bit. Then drill with the largest drill bit in the set that is smaller than the fastener thread being removed.
Drive the extractor into the hole with a brass hammer.
Then unscrew the broken fastener. Use as large an extractor as possible, so that the walls of the drilled stud will become as thin and flexible as possible. The extractor set includes a nut that fits over the extractor. Slide the nut down the flutes. Then grip the nut with a pair of wrenches (to exert equal force) and turn the extractor counterclockwise.
