How do you take out a broken screw, and how do you take out a broken screw?

Screws are a very common small accessory in our lives, which are used in our lives, all kinds of furniture, industrial crafts can not be separated from screws, but in the process of our use, there will be a situation that the implementation is broken and cannot be taken out, so what should we do?

What are the ways to take out a broken screw?

1. If the break is on the outside, it is relatively simple, you can use a hammer to hit it in the opposite direction, and you can slowly withdraw it.

2. Clean up the sludge on the surface of the broken screw, and then use the center to kill the broken place, and then use an electric drill to drill the hole, pay attention to the drilling must be drilled through, take down the small drill bit after drilling, replace it with a relatively large drill bit, and continue to expand the screw hole and drill through.

3. Take a welding rod with a diameter of millimeters, drill holes in the broken screws with a small current, and then carry out surfacing welding, and the arc should not be too long during surfacing to prevent the outside of the broken screws from burning through. Surfacing to 8-10 mm cylinders is required.

4. After welding, use a hammer to hammer the surface to vibrate the broken end. The heat generated by the previous arc cools, which, combined with vibration, loosens the threads of the screws and the body.

5. After knocking, a trace amount of rust will fall out of the point crack, and then you can use the nut sleeve to weld the previously welded cylinder together.

6. After welding, use a wrench to rotate and twist on the nut, and you can easily take out the broken screw.

Tips for using screws.

We can use some lubricant on the screws before using the screws, and then set the position first, and then install the screws, pay attention to measure the length of the screws and the thickness of the object before using the screws, so as not to penetrate. Before nailing the plank, install screws along the vertical of the wood grain, so that the board is not easy to crack. When choosing screws, it should be noted that the length of the screws should be shorter than the centimeter of the appliance.

If the screw is broken, it depends on how much you still have exposed, and a lot of it is exposed, you can repair a plane on both sides of the screw and remove it with a wrench. If there is no outcropping, it can be taken out with a special tool.

How to take out the broken screws

1. When encountering a broken screw, first of all, we need to grind the broken part flat, prepare a drill bit to drill inside, and the surface of the broken wire will gradually fall off, and then we will use the same size of the tap to go deep. Rotate counterclockwise to remove the broken screw.

2. If you can't take it out, weld an iron rod at the screw of the section, and slowly take out the iron rod with the screws inside, but the technical requirements for welding are relatively high, because if you don't pay attention to it, it is likely that there will be a problem of bad screws.

3. Now there is also a kind of broken wire extractor, which is very convenient to use, you need to find the center point, drill a hole first, and then twist out the broken wire extractor in reverse.

How to take out the screws

1. When screwing the screw, it is easy to appear the phenomenon of slippery wire, in this case, we can first install a small piece of rubber skin on the screw of the sliding wire, the main function is to increase the friction, and it can be taken out by rotating with a screwdriver.

2. Pay attention to the choice of rubber block is not too large, otherwise it is likely to run out of the electric drill, it is best to choose a small piece, you can screw out the slippery wire.

You can use the wire retractor to take it out, and you need to operate it with a hand drill when dismantling, and the speed should be slow, not too high or suddenly accelerated, and the whole process needs to be reversed. Take one end to open the hole first, and then take the other end out. The specific steps are as follows:

1. Install one end of the wire retractor on the hand drill;

2. Reverse and drill a small hole in the top of the worn or broken screw;

3. Install the other end of the wire retractor on the hand drill;

4. Reverse and take out the screws.

As we all know, the main function of the screw is to fix, in the process of use, it is inevitable to encounter some difficulties, such as the screw is broken, the screw needs to be taken out, and then a new screw can be driven, but there is no screw head, less borrowing point, it is more difficult to take it out. So, how do you take out a broken screw? What should I pay attention to when using screws?

Let's take a brief look at it together.

1. How to take out the screw when it is broken.

First, use the positioning pin to make a positioning eye in the center of the screw, determine the specifications of the screw at the same time, and choose a smaller drill bit according to the size of the screw; Then punch a hole in the position of the positioning eye, pay attention to the angle must not be deviated, otherwise it is easy to damage the thread, and the screw cannot be taken out; Finally, use a left-hand tap to slowly screw out the broken screw.

Second, what need to be paid attention to when using screws.

1. According to Qeeka Home experts, there are many types of screws, and if you want to ensure the effect of fastening, you must choose suitable screws according to the actual situation, such as aluminum alloy doors and windows, suitable for self-tapping screws, and handrails are suitable for using expansion screws.

2. Different types of screws, the way of nailing is also different, ordinary screws are set well, and they can be knocked in directly with a hammer, while self-tapping screws need to be punched or driven with the help of an electric drill, and nails must be shot with a nail gun, so as to achieve the best effect.

3. Consumers should choose screws of moderate length according to the situation of the connectors, and pay attention to the screws should not be too short, otherwise the occlusion is not enough, and the firmness cannot meet the requirements, and the same should not be too long, otherwise the length of the connector will be exceeded and it is easy to hurt others.

4. Although the surface of the screw is galvanized or painted, there may not be rust in a short time, but if the nail is easy to wear, it is necessary to take corresponding protective measures, otherwise the surface paint film will fall off, and it is easy to rust.

Summary: The above about how to take out the broken screws, and what need to be paid attention to when using screws, I hope it will help you. If you want to know more about related information, please pay attention to Qeeka Home.

Take out the broken screws first to prepare tools, after the preparation of the bureau He Wei is completed, you can use the pins to make a positioning hole in the screw section, use a hand drill to make a hole in the positioning hole, remember that the model should be smaller. After driving the tap in, slowly rotate the tap to the left, so that you can slowly screw out the broken tongpei screw by the way.

Prepare tools: stones or bricks, awls, hand drills, pins, etc.

If you want to take out the broken screw, first of all, you should use the pin to make a positioning hole in the section in the middle of the screw, and then you can use a stone to smash the pin into the section after aligning the pin, and it is convenient to drill and punch the hole after positioning.

Choose a model that is smaller than the broken screw, so that you can avoid drilling the external thread inside when drilling. Once you have selected the drill type, you can start drilling holes according to the positioning holes.

When shooting holes in the state, the tap must be rotated to the left, otherwise the bolt will be broken. After drilling, you can rotate it slowly so that the screw is exposed from the outside of the bolt, so that you can gently twist the tap out, and pay attention to the direction to the left.

When the tap is successfully screwed out, the broken screws will be screwed out together, remember to clean the section and screw mouth to see if there is wear.
