ISO7380 Hex Socket Pan Head Screw Grade10
ISO7380 Hex Socket Pan Head Screw Grade9

There are many types of screws, one is called hexagon socket screws. When purchasing, the salesperson will also ask you which type to choose. Originally, there are many classifications of hexagon socket screws.

There are several types of hexagon socket screws
1. There is a type of hexagon socket screw called pan head. After the screw is installed, its head protrudes on the surface, which makes it more convenient to screw the screw later. This product can be seen on some household appliances.

2.There are countersunk head hexagon socket screws, which means that it will not protrude from the surface after screwing, and it will not affect the appearance. However, if there is a problem that is difficult to screw when screwing, the screw cannot be started.

3.There are also cylindrical head hexagon socket screws, which are similar to the second type of screws. They are relatively strong and require a wrench of the corresponding specification to remove the screws. Generally speaking, they are used on machine tools.

The screw is rusted and can’t be unscrewed, what should I do?
In life, many friends have encountered similar problems. Once the screws are rusted, no matter how much effort is used, they cannot be unscrewed. Because the screw is exposed to the air, if the surrounding environment is relatively humid, after a long time, it is prone to rust. In fact, don’t use brute force, you need to master the skills of screwing.

Tap it first, tap the corroded screw with a wrench, and tap the handle lightly, because if the corroded part is loose, it can be unscrewed later.

If it still doesn’t work after tapping, you can drop a small amount of oil, and then rotate it gently with the wrench a few times. If you don’t have oil at home, you can also use Coke because it will remove rust.
