How do I choose between 4 torque levels and single-torque electric screwdrivers?

Choose a 4-torque-level electric screwdriver if you work on different screw sizes and delicate electronics. Choose a single-torque model if the application is repetitive and always uses the same screw and fastening requirement.

A practical comparison:

4 torque levels: better for phones, laptops, cameras, watches, drones, and mixed electronics repair

Single torque: better for simple assembly work where the screw size and material stay consistent

4 torque levels: gives more control and reduces the risk of over-tightening small screws

Single torque: easier to operate and usually lower in cost

4 torque levels: more flexible for repair shops and technicians working on different devices

Single torque: suitable for dedicated production stations with one fixed fastening task

For delicate repair work, adjustable torque is usually the better choice because the user can start low and increase only when necessary.

ToolQeen multi-stage precision electric screwdrivers provide 0.05, 0.15, 0.25, and 0.35 N·m electric torque levels, with manual operation available for final tightening.

For OEM projects, ToolQeen can also evaluate custom torque values, speed, automatic-stop behavior, motor, gearbox, and PCB control according to the target application.
