Electric Screwdriver is an important tool on the assembly line. Only if suitable tools are used, is it possible to increase the work productivity.
How do you purchase the suitable Electric Screwdrivers? 
The first thing to consider is the range of the torque and its accuracy for the screwdriver. Only if the range of the torque can cover the desired value (the maximum value of the torque value of the screwdriver must be larger than 1.1 times of the work value to ensure the lifetime of the screwdriver), can the screwdriver achieve the maximum work value. 
Secondly, the malfunction rate of the screwdriver, its lifetime, and the customer services of the provider and its ability to provide all kinds of answers to questions and inquiries are also options to be considered during purchasing.
