If you are a business owner or a common man, you may have come across different types of screw tightening machines. Typically, tightening a screw is a piece of cake using a screwdriver. However, sometimes, the screw is located in a hart-to-access area. So, it's not possible to grip or rotate it safely. In this situation, the best way is to use an automatic screw tightening machine. Let's take a closer at some of the most common features of these machines.

1. Maximum Torque

As far as the physical definition is concerned, torque refers to the rotational force that you exert on a specific body. The majority of these machines offer a torque (rotational force) of a minimum of 100N/m. So, this amount of force is more than enough to get the job done.

If you make use of this type of automatic machine, you can tighten screws into solid materials just like a regular drill. The good thing is that you can adjust the torque based on the type of screws you want to tighten. So, these units offer a lot of flexibility to meet the needs of different users.

2. The Rotation Speed

In case you don't know, the rotational speed refers to the number of revolutions in a given period of time. The beauty of a screw tightening machine is that it allows you to adjust the speed at which you can unscrew or tighten an apparatus.

Although different machines offer different rotational speeds, most machines feature a rotation speed of up to 550 per minute. Taking into account the rotation speed, it's possible to adjust the torque using the speed regulator and a special screwdriver.

3. The Batteries

Based on the type of battery the unit comes with, it's possible to work for several hours. As you may know, batteries provide backup time for a piece of equipment. Therefore, before you buy a screwdriver, we suggest that you consider the type of battery first.

Make sure that the battery comes with your desired capacity and supports the voltage in your country. If you are interested in buying a domestic unit, know that these units come with nickel-cadmium batteries.

Also, keep in mind that these batteries can't be charged or recharged after a certain period of time. In other words, they won't be usable once they have been charged and discharged after, say, 10000 times.

Long story short, these are just some of the primary features of screw tightening machines. If you are looking to buy one, we suggest that you look for an automatic screw tightening machine to meet your needs. These machines are quite powerful, which is they can be a good choice to meet your business needs.
