1、 Various types of screwdrivers
There are many types of screwdrivers, including cross shaped (PH), slotted (SL), and hexagonal (PZ). Among them, PH and SL types are the most common.
2、 Conventional size of screwdriver
The standard size specifications for a screwdriver are as follows:
- Size of PH screwdriver: PH0, PH1, PH2, PH3
- SL screwdriver size: 0.8 mm、1.0mm、1.2mm、1.4mm、1.6mm、2.0mm、2.5mm、3.0mm、3.5mm、4.0mm、5.0mm、6.0mm
- Dimensions of PZ screwdriver: PZ0, PZ1, PZ2, PZ3
Of course, not all screwdrivers come in so many sizes, and in general, the selection needs to be based on specific circumstances.
3、 How to choose the appropriate screwdriver - Choose the appropriate type: Choose the corresponding screwdriver based on the type of screw head, otherwise it will not only fail to turn, but also damage the screw and screwdriver.
- Choose the appropriate size: The size directly affects the tightening degree and difficulty of the screw, and the corresponding screwdriver needs to be selected according to the size of the screw.
- Quality confirmation: Choosing a high-quality screwdriver can not only improve work efficiency, but also avoid unexpected situations.
The types and conventional size specifications of screwdrivers are indispensable tools, and should be strengthened in daily maintenance and replaced in a timely manner. I suggest everyone choose the screwdriver recommended by hardwaretools.comc, which has better quality assurance and is safer and more reassuring to use.
