A screwdriver is a tool used to tighten screws to force them into place. Usually, there is a thin wedge-shaped head that can be inserted into the slot or notch of the screw head - the Beijing Tianjin Hebei dialect is called a cone, and places such as Shaanxi, Anhui, Henan, Hubei are called elevators. The following series will introduce the types and specifications of screwdrivers, hoping to be helpful to readers.
A screwdriver, also known as a screwdriver, is a manual tool used to tighten screws to force them into place. Usually there is a thin wedge-shaped head that can be inserted into the slot or recess of the screw head. The Beijing Tianjin Hebei dialect is called "cone", while Shaanxi, Anhui, Henan, and Hubei are called "qi zi". There are mainly one character (minus sign) and a cross (plus sign). There are also hexagonal screwdrivers, including inner and outer hexagons.
What types of screwdrivers are there?
1、 Ordinary screwdriver
This is a screw batch made of a head handle, which is easy to prepare as long as it can be used, but due to the many different lengths and thicknesses of screws, it is sometimes necessary to prepare many different screw batches.
2、 Combination screwdriver
When installing different types of screws, only the screw driver head needs to be replaced, without the need for a large number of screw drivers. The advantage is that it can save space, but it is easy to lose the screwdriver head.
3、 Electric screwdriver
As the name suggests, an electric screwdriver uses an electric motor instead of manual installation and disassembly of screws, usually a combination screwdriver.
4、 Clock driver
It belongs to the precision screwdriver and is commonly used for repairing hand clocks, hence its name.
5、 Small diamond screwdriver
The head handle and body length are smaller than commonly used screwdrivers, not clock drivers.
In terms of its structural shape, there are usually the following:
1. Straight. This is the most common type. There is a character for the head shape, such as a cross, beige, T-shaped (plum blossom), H, and so on
2. L-shaped. It is commonly seen in hexagonal screwdrivers, which use their longer stem to increase torque and save effort.
3. T-shaped. The automotive repair industry is widely used.
Screwdriver specifications
1. The screwdriver model represents the width of the blade * the blade. For example, 2 × 75mm, with a blade width of 2mm and a rod length of 75mm (non full length).
The model of the cross screwdriver is the size of the blade * the blade. For example, 2# × 75mm, blade No.2, metal rod 75mm (non full length). Some manufacturers use PH2 to represent 2 #, but it is actually the same. You can roughly estimate the size of the tool holder, but in industry, you can distinguish the size of the tool holder. The thickness of the metal rods corresponding to 0 #, 1 #, 2 #, and 3 # is approximately 3.0mm, 5.0mm, 6.0mm, and 8.0mm.
What are the specifications of commonly used screwdriver models?
Star hexagonal: T3, T4, T5, T6, T7, T8, T9, T10 (almost all hexagonal screw phones can be disassembled)
M-shaped (U-shaped, fork): M2.6 (U-shaped screwdriver type screwdriver specification)
Y shape (triangle): Y2.0, Y3.0 (Y mobile phone screws, PHS, seat charger, etc., all in one)
▲ Type: 2.0, 2.3 (some triangular screws are rarely used, but spare ones are still needed)
★ Type: 1.2 (special hexagonal screw phones are also included)
Cross: 1.0, 1.5, 2.0, 3.0 (PSP, MP4, MP3, digital, etc.)
Word: 1.0, 1.5, 2.0, 3.0 (clock series)
Inner hexagonal: H1.5, H2.0, H2.5, H3.0, H4, etc
A screwdriver does not have a round head because the round head does not twist at all. One word is to ensure distortion, the cross can make the force distribution more uniform. One word is to ensure distortion, crossing can make the force distribution more uniform. Manual screwdriver and electric screwdriver and electric screwdriver; Divide into one character and a cross based on the batch head or cutter head.
The industry is based on batch headers. It comes in two sizes. One is the metric system, which we often refer to as the unit of measurement. For example, the size mentioned upstairs. There are also English sizes, measured in inches, such as 1/4 or 3/16. Multiplying this number by 25 is the metric size.
The blade of a high-quality screwdriver is made of high hardness spring steel. A good screwdriver should be hard but not brittle, with gaps in its hardness. When the screw head opens and the bald head slips, a hammer can be used to strike the screwdriver to cut the screw groove deeper, making it easier to unscrew the screw. The screwdriver should be undamaged; Screwdrivers are often used to pry things and require a certain level of toughness.
