The bolt breaks off when it is turned sharply or due to other careless actions. The whole difficulty of this situation lies in the fact that part of the fastener is firmly stuck in the inlet hole and is very difficult to remove without special tools. Sometimes it is still possible to pick up a piece of a bolt with pliers and unscrew it, but using an extractor will be much better and more efficient, i.e. a special tool designed for unscrewing bolts.

Purpose and principle of operation

Screw fastenings may be damaged. You cannot do without a special tool for removing broken bolts. It doesn’t matter whether the cap or the rod itself falls off. To unscrew them you need to grab onto something. For these manipulations, manufacturers have developed and filled the market with popular models of extractors.

The main area of ​​application of the device is in machine and furniture repair shops, as well as in construction and repair work on sites. He is an indispensable assistant for unscrewing damaged screws, self-tapping screws, dowels and nails. Using small extractors, you can disassemble folding knives or other screw-mounted structures.

There are many varieties of such devices. They differ in functionality, size, characteristics, design features, and are used to perform a specific task. The most suitable device is selected.

Operating principle:

1. A hole is drilled in the center of the broken bolt or stud.
2. A screwdriver wedge is driven inside.
3. After complete engagement, the process of removing fastener fragments begins.
4. Take a regular open-end wrench or a special tap holder. Holding the shank of the screwdriver, the damaged hardware is slowly unscrewed.

Idle cranking must be avoided. To do this, you need to expend strength and press the tool tightly against the fragment being removed. This will help achieve reliable grip. The extractor is firmly engaged in the body of the broken device. Further manipulations lead to the fastener unscrewing along its thread.

Technology for unscrewing broken bolts

Even a beginner can remove broken fasteners from the base using an extractor. The main thing is to consistently follow all the structural steps of the extraction process. First of all, you should make a mark in the center of the broken fastener, for which you use a punch and a hammer. Then you need to drill a hole where the extractor will be inserted. In this case, the diameter of the future hole is taken into account, since it must correspond to the diameter of the extractor. For this purpose, a special guide bushing is used, which is supplied in the extractor kit. Then you need to install the extractor in the hole you have made, and fix it by tapping it with a mallet or hammer. Next, the extractor is screwed into the hole of the broken fastener using a driver, tap or wrench (all the way). Having screwed the extractor to the limit, you can begin to remove the bolt.

IMPORTANT! It is always worth remembering that you need to rotate the tool only in the direction of the axis, because any displacement will lead to breakage of the device.

Upon completion of eversion, the extractor is carefully removed, preventing damage to the edges of the wedge equipment. If a screw type was used, then the bolt is simply unscrewed. To facilitate the removal process, it is allowed to use a wrench or pliers.

Some features of the application of bolt extraction technology

Depending on the current situation, the technology for removing a broken bolt may vary depending on the location where it is stuck:

1. Below the plane of the base - in this case, you first need to insert a sleeve into the resulting depth so that its diameter matches the hole. Then you need to drill a hole of the proper depth. If the stuck fastener has a large diameter, then small drills are used first to gradually drill out the hole. The final step will be driving in the rod and installing the sleeve to remove the fastener.
2. Above the base plane - in this situation, all the same actions are performed as in the previous one. First, the sleeve is directed and installed, only then a hole is drilled to install the rod, which will remove the stuck bolt.
3. At the same level with the base - here you will have to use a center punch in order to correctly mark the center of the future hole. Then you need to drill a hole in the center, install the extractor and unscrew the pin.

Useful tips when working with threaded bolts

When unscrewing such broken fasteners, it is possible to somewhat simplify the work process:

• If you heat up a stuck product, removing it will take much less time;
• If the thread is broken, you can use a hex wrench to unscrew it;
• Before starting work, it is better to treat the broken part with some kind of lubricant - solvent, acetone or oil;
• Using drills with reverse threads it is very easy to remove a broken bolt;
• Using a core and hammer can be an effective step. The core is installed at an angle of 45 degrees to the broken bolt and is driven counterclockwise. This operation must be carried out on at least four sides, and then the fasteners must move.

Device and device types

The range of popular models is impressive. However, regardless of the manufacturer, there are two types of extractors for metalwork:

• internal;
• external (external).

Internal devices are divided into the following subtypes:

• one-sided;
• double sided

The internal devices have an oblong shape. Working end one or two. Single-sided screwdrivers are equipped with one wedge-shaped or cone-shaped working area with a right (left) thread and a short pitch. The second side is equipped with a shank in the form of a square or hexagon. On sale there are one-sided models, on the back of which a head with a hexagonal or square mouth is attached.

Both ends of double-sided extractors are working. On one side there is a short drill. They drill holes of the required diameter. The other end is equipped with a left-handed tapered thread. Bilateral devices are available in small sizes. They look like screwdriver bits.

The kits may contain guides for external devices that are used for precise alignment. This allows you to avoid damaging the body of the object during careless manipulations.

The external products resemble impact sockets for impact wrenches. However, there are sharp edges inside them, reminiscent of smooth curls. The socket impact heads are devoid of such elements. Some mechanics use impact wrench sockets to remove broken bolts. This leads to premature failure of the device.

All manufactured products are divided into three main categories:

Design features and specifications of individual devices

In addition to the main types of extractors, there are other types of designs. What are they? On store shelves you can find the following products:

1. Rod. An analogue of a cylindrical rod with longitudinal cutting edges. There are grooves between them. Drives into the center of the broken fastener. No pre-drilling required. The sharp edges fit tightly into the damaged hardware, which leads to reliable engagement. The other edge is equipped with a special nozzle with a tetrahedral shank, which is grasped with a wrench or wrench to deal with broken fasteners. According to buyers, the device is not very convenient, since it gets very stuck in the element being pulled out.
2. Extractor – drill. The working end of the screwdriver resembles a left-handed drill. Faces – with cutting edges. It cuts into damaged screw fasteners on its own. After a tight jam, it is possible to remove the broken object.
3. For a screwdriver. What to look for when choosing? The models are compact and are available in single-sided and double-sided versions. The body resembles a hexagonal rod. Can be used as a separate hand tool or as an attachment to a screwdriver. They are sold in sets that also contain guide bushings, knobs and drills.
4. Combined. The set of characteristics of the rod and wedge-shaped analogues. The shape is wedge-shaped. The grip is excellent due to the presence of a large number of sharp edges. The device is driven into the center of the hardware being removed using a hammer. Once engaged, it can be twisted both to the right and to the left.
5. Eccentric. The second name is a stud gun. Produced with an offset center. Area of ​​use: unscrewing studs. The device is interesting. Allows you to unscrew a screw type fastener with a head with worn edges or without a head. Belongs to the category of specialized devices. The only limitation when using the device is that it will cope with the task if there is a place to grab onto. If the bolt body is completely embedded in the object, the eccentric product will be powerless to do anything.
6. Secret extractor. The characteristics resemble an extractor in appearance - the best for extracting secret bolts from car wheels. A distinctive feature is the thickness of the walls. They are thinner so that they can be placed freely on the head of the wheel bolt without damaging the alloy wheels.
7. Reinforced. A distinctive feature is the material of manufacture. The composition contains special additives that increase the strength index. This allows you to extend the life of the device and make it more reliable.
8. For pipes. The main purpose is to remove pipe scraps, as well as various adapters in the sewer system. A conventional tool will not achieve the desired result. In appearance and operating principle it resembles a screw extractor, only the dimensions are significant. There is no need to drill a hole in the pipe. It is present initially and the device is screwed into it. After jamming, it is unscrewed together with the broken part of the pipe.
9. Universal. With the function of extracting pipes or individual parts thereof, if it is not possible to get hold of it with another tool. Copes with all pipes, regardless of their diameter. The main thing is that the maximum size of the device itself is sufficient. Works in a similar way to an internal thread extractor. Suitable for other uses.
10. Hydraulic. Belongs to the category of professional tools. The main purpose is to turn out rolled pipes. Belongs to the manual category. The dimensions are significant. Place of use: industrial production facilities.

How to choose the right product? It is necessary to decide on the scope of its use. This is the main selection criterion. Which product is better to buy depends on many factors, including the user’s personal preferences. You cannot make mistakes when choosing. Otherwise, a positive result will not be achieved.

The reliability and durability of the structure depends on the correct choice. It is worth noting that inexpensive devices made in the Middle Kingdom cannot be of high quality.

Where to buy devices? Experts advise visiting specialized retail outlets, getting acquainted with the presented assortment, holding the selected model in your hands, and determining the quality of the assembly and materials used. If necessary, you can get advice from a professional sales manager. You can order tools online in the online store. You need to treat such a purchase carefully, as there is a chance, instead of an expensive device from a leading foreign manufacturer, to become the happy owner of a disposable budget Chinese counterfeit with questionable performance characteristics.

Main characteristics of devices

It is worth noting that extractors are designed to perform strictly defined tasks. They help remove a fastener with a broken head from an object. An indispensable item for car repairs. Much attention should be paid to such properties as the reliability and strength of the material used in manufacturing. The product is produced from high-carbon steel, carbide metals, and high-speed steel. S2 tool steel, oxidized steel, high-strength chrome vanadium steel and other similar alloys are often used.

It is worth noting that underground manufacturers use soft metals to manufacture products, which makes the use of these tools for their intended purpose impossible. Therefore, it is necessary to pay special attention to the manufacturer and labeling. You should not contact little-known companies or those whose products have complaints. This is fraught with loss of money.

The weight of the device depends on the metal used in its manufacture, as well as on the parameters and type. Internal extractors have lengths from 26 to 150 mm. Conical tip in the range of 1.5 - 26 mm. The weight of the structure is 8 – 150 grams. External products are available in lengths from 16 to 26 mm, weighing about 100 - 150 grams.

There are no GOST standards for these locksmith devices. Each manufacturer relies on its own specifications. Well-known brands have personal laboratories where specialists develop the best composition of materials for the manufacture of professional-level instruments. Product markings are either missing or the diameter for which the tool is suitable is indicated.

What metals are extractors made from?

In short – titanium and alloy steel. But some rare alloys are also possible. Usually people assume that everyone has become the same, but this is not true. Steel, by definition, is an alloy metal consisting primarily of iron and carbon, as well as other trace elements. It has high tensile strength and is relatively inexpensive to produce, making it a popular metal used by manufacturing companies.

However, there are different types of steel, each with its own characteristics. For example, carbon steel is often preferred over other types of steel.

Carbon steel

It is a special type of steel that, as the name suggests, has a higher concentration of carbon than other types of steel. Most types of steel have a relatively low carbon content, approximately 0.05 to 0.3%. In comparison, carbon steel has a carbon content of up to 2.5%. Two and a half percent carbon may not seem like much, but it offers several attractive benefits that other metals do not.

Advantages of Carbon Steel

There are several advantages to choosing carbon steel over traditional steel, such as increased strength. Using carbon makes iron or steel stronger by shuffling its crystal lattice. Although carbon steel can still be stressed and fail under pressure, this occurs less frequently than with other types of steel. This makes it especially effective in applications where strength is required.

For example, Japanese blacksmiths made swords from high-carbon steel known as tamahagan centuries ago. Today, carbon steel is used to make extractors, cutting tools, fasteners, etc.

Disadvantages of Carbon Steel

But there are also some disadvantages to choosing carbon steel over traditional steel. Because carbon steel is very strong, it is difficult to work with. It cannot be easily bent and molded into different shapes, which limits its use in certain applications.

Carbon steel is also more susceptible to rust and corrosion than other types of steel. To make it "stainless", manufacturers add chromium - usually from 10% to 12%. The chromium acts as a protective barrier to the steel itself, thereby protecting it from moisture that would otherwise cause rust. Carbon steel, however, does not contain chromium, so it can rust if exposed to moisture for long periods of time.

Titanium extractor

One of the most noticeable advantages of titanium is its strength. It is one of the strongest and most durable metals on the planet, which is why it is used in many industries. In fact, titanium has the highest strength-to-density ratio of any metal element on the periodic table, demonstrating its advantages. Titanium (unalloyed) rivals steel in strength but is less dense, making it the preferred choice among many professionals.

Another advantage of titanium is its natural resistance to rust and corrosion. When metal is exposed to moisture, it triggers a chemical process known as oxidation, which can subsequently lead to corrosion. Whether used indoors or outdoors, it will last for years without succumbing to rust and corrosion.

Flaws

Of course, titanium also has some disadvantages. For example, the difficulty of casting, in contrast to iron and aluminum.

It's also worth noting that titanium tends to be more expensive than other types of metals. Compared to steel, iron, aluminum, etc.

Difficulty of choice

It’s worth mentioning right away that the quality of the equipment in question is the determining parameter that should influence the choice. Extractors should not be purchased randomly and without careful analysis of all their operating properties. The characteristics that determine the quality of the extractor include the strength properties of the material used to make it. The steel must be very hard, but not very brittle, otherwise the tool will simply break during operation. Only a few grades of steel from different manufacturers have such characteristics, but in their composition they are more or less very similar to each other. Unfortunately, some manufacturing companies from Asian countries make extractors from almost any type of steel that is somewhat durable. Indeed, such products have a lower cost, but their purchase will not bring much benefit, and the tool itself can only be used a couple of times, then it will break. Therefore, experts advise buying only those sets whose manufacturer does not raise reputational doubts, while at the same time paying attention to the markings of the steel used in the tools.

Modern samples of extractors are sold both separately and as part of various sets. Professionals recommend having a complete set with extractors of different diameters and sizes on hand, and it would also be nice if the kit comes with additional tools. Naturally, the cost of a high-quality and complete set may seem quite high, but all expenses will pay off after the first use.

What you need to know about extractors?

The edges of extractors made of soft metals quickly lick off, and such a tool becomes unsuitable for work almost from the first minutes.

Soft metals are most often used in the manufacture of tools by Chinese gray manufacturers, which makes the price of their products even lower.

You shouldn’t chase cheapness; it’s better to buy a professional tool made from quality materials once, which will serve for a long time.

Important!

Chinese instruments can also be of high quality and professional, it all depends on the manufacturer.

Fake extractors with false labeling are often found even in specialized stores; to avoid being deceived, ask the seller for certificates of conformity.

It is more profitable to buy sets of extractors, the kit of which includes several different tool sizes; sometimes there is also a wrench or a special attachment for a tetrahedron or hexagon.

There are also kits that come with a guide sleeve, which makes it much easier and simpler to drill a hole in the stuck hardware strictly in the center.

In addition, the extractor sets are placed in special cases or cases; storing and transporting the tool in such boxes is much more convenient.

Benefits of using extractors

The use of this type of device for removing tightly stuck bolts has several undoubted advantages:

• The tool is quite simple to use: to handle it successfully, no special knowledge or skills are required;
• Sets of such tools are quite affordable, which indicates their universal popularity;
• The set includes most extractor tools with the most common diameters and sizes;
• Using this tool, you can quickly unscrew almost any damaged fastener stuck in a car body, furniture or equipment;
• If extractors are made of high-quality and durable steel, then the likelihood of their breakdown is very low, and on the contrary, their service life increases sharply.

Of course, not every bolt can be removed using an extractor - situations vary. The main thing is to follow the rule, which states that the material of the stuck element must be softer than the material from which the extractor is made.
