How to remove the screw cap if it slips and cannot be unscrewed?

In our lives, we often encounter some small troubles, such as a screw cap that slips and cannot be unscrewed. When this happens, we might as well try the following methods to solve the problem.
Method 1: Increase friction
First, we can try to increase the friction between the screw cap and the screwdriver. You can use a piece of rubber band or tape to securely tie the screwdriver and nut together to increase the strength and reduce the possibility of slippage. At the same time, you can also try using pliers to clamp the screwdriver blade to provide extra strength.
Method 2: Heat the screw cap
Sometimes, the screw cap may be difficult to loosen due to reasons such as fasteners. At this time, we can try to heat the screw cap with fire. Please note that you only need to heat the screw cap slightly and do not allow it to completely discolor or deform. Because high temperatures may cause damage to the screw cap.
Method 3: Use of lubricant
If the screw cap is very tight or has rust, a good idea is to use lubricant. You can choose lubricant or spray, apply it on the screw cap and rotate it gently a few times. The function of lubricant is to reduce the friction between surfaces, making it easier for the screw cap to turn.
Method 4: Use an anti-slip material
Another simple method is to put an anti-slip material, such as a rubber band, rubber pad or tape, between the screw cap and the screwdriver. This increases the contact area between the screw cap and screwdriver, reducing the possibility of slipping.
Method 5: Seek professional help
If none of the above methods solve the problem, we can consider seeking professional help. You can consult personnel in relevant industries or maintenance service centers for their advice and help. Professionals usually have more experience and more tools to solve these types of problems.
Summary: When we encounter the problem that the screw cap is slipping and cannot be unscrewed, we can try to increase the friction, heat the screw cap, use lubricant, put an anti-slip material, or seek professional help.
