How to choose the torque of electric wrench

When choosing an electric wrench, the choice of torque is very important. Depending on the work requirements and bolt specifications, an electric wrench with corresponding torque needs to be selected. Here are some suggestions for electric wrench torque selection:

1. Job demand analysis: First, the job needs need to be clarified. Different jobs require different torque ranges. For example, different torques are required to fasten building structures, mechanical equipment, pipes, etc. When choosing, make sure the electric wrench you choose can meet the needs of the actual work.

2. Bolt specification considerations: Bolt specification is a key factor in selecting the torque of an electric wrench. Bolts of different sizes require different torques to tighten. For example, M10 bolts require relatively small torque, while M20 bolts require relatively high torque. Therefore, when choosing an electric wrench, you should choose the appropriate torque range according to the specifications of the bolts that need to be tightened.

3. Brand and reliability: Choosing an electric wrench from a well-known brand can guarantee quality and reliability. At the same time, the torque of different brands of electric wrenches may be different, so pay attention to this when choosing. It is recommended to choose a brand that has been tested in the market and has a good reputation to ensure that the electric wrench you purchase has reliable performance and torque accuracy.

4. Trial run and calibration: When choosing an electric wrench, you can request a trial run and calibration. Through trial operation and calibration, you can understand the actual performance and torque accuracy of the electric wrench. This can better evaluate whether the selected electric wrench meets the needs of the actual work.

5. Safety considerations: When choosing an electric wrench, you also need to consider safety factors. For example, you should choose an electric wrench with overload protection and automatic shutdown functions to avoid damage or safety accidents caused by excessive force or overload. In addition, you should also pay attention to the safe operating procedures when using it to ensure safety during the work process.

6. Maintenance and care: After choosing the right electric wrench, you also need to perform correct maintenance and upkeep. Regular cleaning, lubrication and inspection of electric wrenches can ensure long-term stable operation and extend service life. At the same time, you also need to pay attention to using a suitable battery or charger according to the manufacturer's recommendations to avoid damage to the electric wrench due to overcharge or overdischarge.

7. Price factor: The prices of electric wrenches of different brands and models will be different. When choosing, weigh the price factor against your budget and actual needs. Don’t just go for the low price and ignore the quality and reliability of your electric wrench. It is recommended to choose products with high cost performance to ensure long-term stable performance.

8. Usage environment: The usage environment is also one of the factors that need to be considered when choosing an electric wrench. For example, when working in a humid and dusty environment, you should choose a waterproof and dustproof electric wrench. When working in special environments such as high and low temperatures, you need to consider the temperature resistance and adaptability of the electric wrench.

9. Personal habits and experience: When choosing an electric wrench, personal usage habits and experience will also have an impact. Some people may prefer an electric wrench that is lightweight and easy to operate, while others may be more focused on torque and precision. Therefore, you can make decisions based on your own habits and experience when choosing.

In short, when choosing an electric wrench, you need to comprehensively consider multiple factors such as work requirements, bolt specifications, brand and reliability, trial operation and calibration, safety considerations, maintenance and upkeep, price factors, usage environment, and personal habits and experience. By weighing these factors, you can find the electric wrench that best suits your needs and ensure it performs well on the job.
