When repairing a mobile phone, a screwdrive is required to open the case (some phone cases are hidden without screwdriver). Most screws used are hexagon socket screws; different mobile phones have different specifications, generally T5, T6, T7, T8 etc. Some models are also equipped with special screws that require a special screwdriver. In addition, you need to prepare some small flat and small Torx screwdrivers.
When matching such tools, use sets A and B, which include almost all tools for opening phone cases. To open the housing, use a suitable screwdriver according to the type and specification of the mounting screws on the housing. If unsuitable selection is made, the groove of the screw can be flattened, resulting in slippage.
Screwdrivers do not have a round head because a round head has no torque at all. The word is meant to guarantee torque, and the cross allows a more even distribution of force. Depending on the power source, there are hand screwdrivers and electric screwdrivers; Depending on the batch head or knife head, there are flat heads and cross slots.
The head of a high-quality screwdriver is made of spring steel with relatively high hardness. A good screwdriver should be hard, but not brittle and tough and tough. If the opening of the screw head becomes bare and slippery, you can hit the screwdriver with a hammer to make the groove of the screw deeper, so that the screw can be easily unscrewed out. Don't bend. Generally, it is hoped that the hardness of the screwdriver head is greater than HRC60 and is not easy to rust.
1. Ordinary screwdriver
It is a screwdriver in which the head and handle are assembled. It is easy to prepare and can be used as long as it is removed. However, since there are many different lengths and thicknesses of screws, it is sometimes necessary to prepare many different screwdrivers.
2. Combination screwdrivers
A screwdriver that separates the screwdriver head and handle. When installing different types of screws, you only need to replace the screwdriver head and do not need to bring a large number of screwdrivers. The advantage is that it can save space, but it is easy to lose the screwdriver bit.
3. Electric screwdrivers
Electric screwdrivers, as the name suggests, use electric motors to replace manual screw installation and removal, usually combined screwdrivers.
