Choosing an Electric Torque Screwdriver

Electric Torque Screwdrivers

Electric Torque Screwdrivers

Electric Torque Screwdrivers are versatile tools that can be used to quickly put together assemblies. They control the amount of torque placed onto the screw and ensure that the same torque is consistently applied. This advantage ensures that the screw is tightened correctly and will not become loosening over time, as well as prevents the screw from being overtightened that can lead to damage or breakage. Numerous industries utilize torque screwdrivers, especially those in the manufacturing sector. You will often find torque screwdriver usage high when assembling electronics, medical devices, automobiles and contract manufacturing.

To provide the torque for the screwdriver, different methods may be used. A manual torque screwdriver, where you supply the force, can be used for light duty jobs. For high volume work, electric or air torque screwdrivers are typically sought after.

Choosing an Electric Torque Screwdriver

Choosing an electric torque screwdriver will be based on a wide range of factors. You will need to gather the following information before comparing the different suppliers: the application’s needs, the required RPM, and the required torque.  Then you can choose the right screwdriver that will complete the task.

Application’s Needs

The application that the electric torque screwdriver will be used for will play a big factor on which one to select. Consider the type of project it is, the number of assemblies that will need to be completed in that day, and even whether you will be working in different areas of the shop floor.

For some applications, you may need to move to other locations. In these instances, an electric torque screwdriver with a portable battery will be required. Other applications may allow a plug-in electric torque screwdriver to perform the assembly work. You also want to evaluate the fasteners that will be in use.

Required RPM

A torque screwdriver will have an RPM setting that is often overlooked by customers when selecting a specific tool. Yet the RPM rating is very important as it is the amount of speed that is applied based on the rotations per minute, which can determine the amount of torque that is experienced. A high RPM can be for a shorter duration but have increased inertia. A lower RPM can have less inertia, but it may be applied for a longer length of time.

Depending on the length of the assembly line and whether you are working with hard or soft materials, the correct RPM can ensure the screw is tightened without damaging the material. The screw will also be tightened fully without the risk it falling out later in the assembly process. At lower speeds, you can improve the accuracy and quality of the assembled products but the lower speed can impact the product volume. If high volume output is preferred, higher speeds will be necessary.

Required Torque

The torque offered by these electric screwdrivers is provided by the internal clutch mechanism and provided controls. The mechanism will apply the right amount of force to the head of the screw at the necessary RPM.

Electric torque screwdrivers will have different torque ranges that it can work within. After evaluating the application and determining the amount of torque that is needed based on the torque specifications for the fasteners, you want to select a screwdriver where the application’s torque falls within the middle of the screwdriver’s high and low range.
