Tohnichi STC2-G Digital Torque Screwdriver

Capacity 50 / 200 / 400 cNm

Multi-functional LED ring: operator can visibly and audibly check the torque status and judgement


Tohnichi's digital screwdriver STC2-G is ideal for controlled screw tightening or inspections. Manual screw tightening always represents a risk because fasteners are often overloaded and a fracture hazard. This risk is minimized by the torque screwdriver with LED indicator ring and reversible display.


The STC2-G is powered by a Li-Ion battery pack that allows a continuous use of up to 30 hours. Available measuring units are cN·m, kgf·cm, Lbf·in, and ozf·in. Up to 1000 readings can be stored in the internal memory. STC2-BT equipped with Bluetooth* data communication is also available.


The display of STC2 -G can be reversed, whereby the reading from the respective viewing angle is greatly facilitated. This increases the reliability of results and ease of use.
