The screw is loose. How to take it out?

When the screw slides, the friction can be enhanced by filling the screw head. For example, you can put the waste cloth on the screw head, and then loosen the screw with a screwdriver and take it out. If there is a rubber band, you can put a rubber band on the screw head and unscrew it easily with a screwdriver.

If the screw is slippery, you can also choose to clamp the screw head with pointed-nose pliers, and then you can rotate the pliers to take the screw out, but this method is only suitable for slippery screws with slightly protruding screw head.

If the object fixed by the screw can withstand high temperature, you can insert the tip welding head into the nut, heat the metal screw to melt the plastic around the screw, clamp it with the tip and gently pull it out.

In daily life, screws usually slip because of rust, poor quality and other reasons, so it is best to buy products with better quality when purchasing screws, and consider the use place of screws. Stainless steel screws can be purchased for outdoor use.
