The cross shaped screws are screwed and ground into a round, what should I do?

There are the following ways to solve it:

Method 1: You can use a grinding machine to slice in the screws.

A deep slit was cut on the cap, and the cross was changed to a slotted screw.

Method 2: Fill the middle of the circle with tin, and then twist it out with needle-nose pliers.

Method 3: Put some toilet paper on the hat.

Increase the friction.

Method: pliers can be used.

Clamp the screw riser and rotate to unscrew.

Cross-shaped screwsThe scientific name of a cruciform screwfor Phillips slot screwsPhillips slot screw material:Iron and stainless steel, iron Phillips slots are also called carbon steel screws, stainless steel Phillips slots have stainless steel SUS201 and stainless steel SUS304, stainless steel SUS316 Phillips slot screws.

I have seen a small hole in the screw with a small flashlight, unscrew it with a tap, and send it to a professional repair of electrical appliances.

Dear, hello, I am glad to answer for you, very small Phillips screws are rounded, you can follow the following operation: put something on the screwdriver head, such as double-sided tape, non-woven fabric, etc., if there is really no condition, the paper can also be this way, which can increase the friction. Inject a small amount of 502 glue into the screw hole, then screw the screw in, wait for the glue to solidify, and then use needle-nose pliers to screw out the screw (only so don't use a screwdriver for fear of causing the screw to slip again), and wait for the glue to harden completely.

If the screw cap is exposed, you can use sharp pliers to tighten the screw cap and unscrew it. You can also cut off the screw cap and disassemble the casing before disposing of it. Burn the head of the screwdriver on the gas stove and quickly press it against the screw for about 5 seconds before it can be wrung out.

After heating with an electric soldering iron, put it on the spent screw head for too long, until you can twist the screw, you can find some waste products to practice the feel, so that it is safest to disassemble.

When the screw cross grinds out, you can put something on the screwdriver bit such as double-sided tape, non-woven fabric, etc., or inject a small amount of 502 glue into the screw hole, and then use needle-nose pliers to screw out the screw after the glue solidifies, which can increase the friction.

When the screw cap is exposed, you can use sharp pliers to tighten the screw cap and unscrew the screw, when you can't screw it, you can use the pointed soldering iron tip to insert it into the screw cap, heat the metal screw to heat and melt the plastic around the screw, clamp it with sharp pliers, and gently pull it out.

Screw callout:

The annotation format for thread marks is:

Thread Code – Thread Tolerance Band Code (Middle Diameter, Top Diameter) – Screwed length.

l) The tolerance zone code is represented by numbers and letters (uppercase letters for internal threads, lowercase letters for external threads), such as 7h, 6g, etc., it should be specifically pointed out that 7h, 6g, etc. represent thread tolerances, while h7, g6 represent cylindrical tolerance codes.

2) The length of the rotation is defined as short (denoted by S), medium (denoted by N), and long (denoted by L). In general, the thread length is not marked, and the thread tolerance zone is determined by the medium length of the thread (n). If necessary, the screw-length code S or L can be added, such as "M20-5G6G L".

If it is specially required, the value of the screwing length can be indicated, such as "M20-5G6G 30".

The following methods can be used if the screw is rounded and cannot be wrenched: 1. You can wrap a layer of cloth or paper on the screwdriver to increase friction. 2. Insert the screwdriver into the slot of the screw, turn it counterclockwise, and you can take it out and screw it out.

3. Hit the screwdriver with a small hammer or pliers, shake the cross pattern, and you can screw it out. 4. Switch to a screwdriver with a large number of silver, sharp celery or welding, hot melting, etc. The above are some solutions to the screwdriver that can't unscrew the screw, I hope it will help you.

The screw is rounded and cannot be screwed, and the solution is as follows:

1. You can knock the item in reverse first, or you can use a hammer to hit the state oak, and after the screw is loosened, you can easily take out the screw.

2. You can wrap a rubber band around the screw, which can increase the friction, and then use a screwdriver to screw, and you can save a lot of effort.

3. You can use a knife to engrave a cross on the screw cap, and after carving a certain depth, you can easily screw it out with a screwdriver.

Precautions for buying screws next to the book wheel

1. There are many specifications of screws, and when you buy, you can consider it in combination with the actual situation, and the space for choice is very large. There are large screws, small screws, and expansion screws, and the scope of application of each screw is different, if you don't know which one to choose, it is recommended to consult with a professional before making a decision.

2. Remember to buy screws in a reliable way, you can go directly to the local hardware store to buy, or you can buy online, and go directly to the store to buy, so it is convenient to make comparisons and understand the quality of screws, so it is recommended to take this purchase method as the first choice.

Hello, if the Phillips screw is screwed, you can try the following methods:1Use rubber bands:

Place a rubber band on the Phillips screw head and then tighten it firmly, the rubber band can provide extra friction and help unscrew the spent Phillips screw. 2.Use glue:

Apply some glue to the Phillips screw head and wait for the glue to dry before unscrewing the screws with a screwdriver. The glue can fill the flower part and increase the friction between the screw head and the screw. 3.

Use a rubber tube: Put a small piece of rubber stool rubber tube next to the jujube ball and put it on the screwdriver, and then unscrew the spent Phillips screw. Rubber or hose can provide better grip and friction.

4.Use pliers: Clamp the flowered Phillips screw head with pliers, then unscrew the screws with a screwdriver.

Pliers can provide better grip and friction. If none of the above methods can unscrew the spent Phillips screws, you can consider using a professional tool or seek professional help.
