Bolt extractor - effective solution to a serious problem

The extractor of the bolts is exactly what they remember only when necessary. Although any home-master or car enthusiast, such equipment in a tool box clearly does not hurt. And these are not empty words, but the life dictated by the life of the repairer.

Very often it happens that during the work the screw is broken. As a result, one part of it lies on the floor or the ground, and the other remains in its place. Unscrew the remains with the keys, heads or pliers is no longer possible. Here, in this case, there is a need for an instrument such as an extractor for broken bolts. You can, of course, perform this procedure in other ways, but using specially designed equipment for these purposes will greatly simplify the task.

Extractors for extracting bolts make it possible to remove broken fasteners with threads of different diameters, but the most common kits include M1 to M16. In this case, the technology for turning out broken bolts depends on where the fracture occurred.

The place of breakage below the surface

In this case, a guide bushing of the appropriate diameter must be inserted into the formed recess. Next, make a hole with the appropriate drill as far as possible. If the diameter of the bolt is large, a smaller diameter drill can be used. Then, in the resulting hole, hammer a suitable sized rod with a hammer, then install a bushing on it and unscrew the broken part of the fastener.

The place of scrapping on a level with the surface

In this case, you will need not only an extractor of bolts, but also a punch. With its help, it is necessary to plan the center in the remainder of the bolt. After that it is required to drill a hole, insert a rod with a bushing and unscrew the chip.

The place of breakage above the surface

In this state of affairs, the extractor of broken bolts is used in a similar manner to that in the first case. That is, a guide bushing is installed, then a hole is drilled, a rod with a bushing is jammed and a broken piece of fastener is twisted.

After the chip is removed, it must be removed from the rod. To do this, it is enough to tap it with a hammer. In general, the process of working with such equipment is not too laborious.

Another question is how to choose a bolt extractor. As it was said earlier, people resort to buying such equipment forcibly, i.e., on the fact of scrapping. In this case, the main indicator that you should pay attention to is the thread size. It is necessary that the extractor is suitable for extracting fasteners.

It's a different matter if they are purchased as a security. In this case, it is best to choose a set with a large number of supported thread diameters. Also pay attention to the direction of the thread. And one of the key points of choice is the material from which the bolt extractor is made. More reliable and durable will be sets made of hardened or chrome-vanadium steel.
