How to remove bolts
Removing bolts is a common operation in mechanical repairs and routine maintenance, but improper methods may cause bolt damage or tool wear. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed guide to removing bolts, and attach structured data on related tools and techniques.
1. Common tools for removing bolts
The following are commonly used tools for removing bolts and their applicable scenarios:
| Tool name | Applicable scenarios | Things to note |
|---|---|---|
| wrench | Common bolt removal | Choose a wrench that matches the bolt size |
| socket wrench | Space constrained bolts | Use with extension pole |
| impact wrench | Rusted or stubborn bolts | Avoid thread damage caused by excessive force |
| screwdriver | Hexagon socket or cross bolts | Make sure the blade and bolt fit perfectly |
2. Steps to remove bolts
1.Check bolt condition: Observe whether the bolts are rusted, deformed or damaged, which will affect the choice of disassembly method.
2.Choose the right tool:Select the above tools according to the type and condition of the bolt, making sure the tool matches the bolt exactly.
3.Apply lubricant: If the bolts are severely corroded, you can spray rust remover or lubricating oil and let them sit for 10-15 minutes before trying to disassemble them.
4.Counterclockwise: Most bolts have right-hand threads and should be loosened counterclockwise. If the bolt has left-hand threads (like some bicycle components), it will need to be turned clockwise.
5.Dealing with Stubborn Bolts: If the bolt cannot be loosened, you can use the following methods:
| method | Operating Instructions |
|---|---|
| heating method | Use a heat gun or flame to heat around the bolt and use the principle of thermal expansion and contraction to loosen it. |
| Vibration method | Tap the head of the bolt lightly with a hammer to break up the rust. |
| drilling method | Drill holes in the center of the bolt, destroy its structure and remove it |
3. Hot topic on the entire Internet: Innovative methods of bolt removal
According to the hot content in the past 10 days, the following are the bolt removal techniques hotly discussed by netizens:
| Popular methods | Principle | Applicable scenarios |
|---|---|---|
| Coke soaking method | Use the acidity of cola to dissolve rust | Mildly rusted bolts |
| freezing method | Freeze bolts with liquid nitrogen to cause them to shrink | Bolts tightened in high temperature environments |
| electric shock method | Generating heat and vibration through electric current | Industrial grade stubborn bolts |
4. Precautions
1.Safety first: Wear gloves and goggles when removing bolts to prevent tools from slipping or debris flying.
2.Avoid violent disassembly: Excessive force may cause bolts to break or tools to be damaged, making repairs more difficult.
3.Check threads: Clean the threads of bolts and screw holes after disassembly to ensure normal use during next installation.
4.alternative: If the bolt is completely damaged, consider using a bolt extractor or drilling and tapping directly.
5. Summary
Removing bolts requires choosing the appropriate method and tools based on the specific situation. By combining traditional techniques with innovative methods popular around the web, disassembly tasks can be completed more efficiently.
