Both screwdrivers and electric wrenches are mechanical electric tools that are widely used in field of machining, maintenance and assembly, which can improve work efficiency and productivity. But there are some differences between them, let's take a closer look below.
1. How it works
A screwdriver is a hand-held electric tool mainly used to turn screws and nuts, and an electric motor drives screwdriver head to drive screws and nuts into or out of a target. An electric wrench is also a hand-held electric tool, but its working principle is that electric motor drives head of wrench, and it is mainly used to tighten and loosen bolts and nuts.
The main function of a screwdriver is to drive and unscrew screws, screws, nuts, etc., so it has a wider range of use cases and is suitable for mechanical connection operations in various maintenance, assembly and manufacturing processes. The main function of electric wrench is to tighten and loosen bolts and nuts, so it is mainly used for assembly and disassembly of large machinery and equipment or vehicles.
3. Work efficiency
Electric wrench plays a more prominent role in assembly and disassembly of large mechanical equipment, and with large tightening torque and high speed, work efficiency is higher. In contrast, screwdrivers are more convenient when assembling or disassembling small parts and are more versatile in use.
To sum up, screwdrivers and electric wrenches have their own characteristics, and they must be selected according to the actual needs during use.
