We often use tools such as bolts and screws in our daily lives, so we don't know what to do after the screw is broken. At this time threading tools are useful.
A bolt is a mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten and connect two parts through holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is detachable.
If the bolt is large enough, you can use a reverse tap, that is, first drill a hole on the cross-section of the bolt, and then use the reverse tap to unscrew the bolt. The bolt extractor is also called the broken wire extractor. The tools needed when using it: bolt extractor, wringer, pipe wrench, or wrench. Take out the broken wire extractor, install it on the twister, and tighten the twister so that the broken wire extractor will not loosen in it.
