Area of application

These torque adapters are suitable for particularly low torques. The torque value is preset in the adapter and can be clamped between any standard holding tool and a 4 mm bit. This turns any bit holder into a torque screwdriver, for example for working on watches, circuit boards, drones, consumer electronics, smartphones, tablets, PCs, or other communication devices.

Technical product description

Precise and accurate, for 20,000 clicks. Adapters are primarily suitable for manual operation. When used with power tools, we recommend a maximum speed of 100 rpm with minimal click repetition. Higher speeds are possible as custom-made products, please contact us!

General information

Turn your bits and a holder into your perfect torque tool. Conveniently combinable with preset torque for tightening or loosening. These high-precision precision tools are available from 0.1 to 0.7 Nm and are used in combination with 4 mm bits. Often used as a complete solution for work on electronic devices, in quick-change systems, robot stations, aerospace, medical technology, or simply on any workbench where precise torque is required. The click sound indicates when the torque has been reached, so that the adapter cannot be overtightened. When loosening screws, there is no torque release (due to the locked core shaft), so no additional loosening tool is required.
