Mutterinvääntimet

Mutterinvääntimet, often translated as nut runners or nut spinners, are specialized tools used for tightening or loosening nuts. They are typically powered by electricity or compressed air and feature a rotating head designed to engage with the hexagonal shape of a nut. The primary advantage of a mutterinväännin is its speed and torque, allowing for significantly faster operation compared to manual wrenches. This makes them particularly useful in industrial settings and assembly lines where repetitive nut fastening is common.

These tools come in various forms, including inline nut runners, where the motor is aligned with the output shaft, and right-angle nut runners, which allow access to nuts in tight or confined spaces. The output torque of a mutterinväännin can often be adjusted to prevent overtightening, which can damage the nut, bolt, or workpiece. Some advanced models also incorporate features like automatic shut-off when a preset torque is reached, ensuring consistency and accuracy. The selection of a specific mutterinväännin depends on factors such as the size of the nuts, the required torque, the available power source, and the working environment.
