Screwdriver head type classification:
Screwdrivers can be divided into one word, cross, rice, star (computer), square head, hexagonal head, Y-shaped head, etc. according to different head shapes. One word and cross are the most commonly used in our life, like Installation and maintenance should be used. It can be said that a screwdriver is needed whenever there is a screw. Hexagonal heads are not used much.
Hexagonal wrenches are commonly used. Like some machines, many screws have hexagonal holes for convenient multi-angle force. The star-shaped big sees not much. The small star type is often used to dismantle mobile phones, hard disks, notebooks, etc. We call small screwdrivers like clocks, commonly used star type T6, T8, cross PH0, PH00.
Making material
The screwdriver has no round head because the round head has no torque at all. The word is to ensure that there is torque, and the cross allows the power to be distributed more evenly. According to the power source, there are manual screwdrivers and electric screwdrivers; flat heads and Phillips are divided according to the head or the cutter head.
The tip of a high quality screwdriver is made of spring steel with a relatively high hardness. A good screwdriver should be hard and not brittle, and hard and tough. When the screw head opening becomes bald and slippery, you can use a hammer to tap the screwdriver, and the slot of the screw is deeper, so that the screw can be unscrewed. The screwdriver is often used to pick up things, and it requires a certain degree of toughness. Bend is not folded. In general, it is desirable that the hardness of the head of the screwdriver is greater than HRC60 and it is not easy to rust.
basic skills
When repairing the mobile computer, you need to use a screwdriver to open the case (some mobile phone cases are dark-button type without a screwdriver). Most of the screws use hexagonal screws; different mobile phones have different specifications, generally T5, T6, T7, T8, etc. Some models also have special screws, need a special screwdriver.
In addition, you need to prepare some small screwdrivers and small plum screwdrivers. In the selection of such tools, the A and B sets should be used. It includes almost all the open-shell tools of mobile phones. When opening the case, select a suitable screwdriver according to the type and size of the fixing screws on the case. If the selection is not appropriate, it is possible to flatten the slot of the screw and cause slippage.
