STC200CN2-G-BT Digital Torque Screwdriver, 40～200 cN.m w/Bluetooth

Tohnichi STC200CN2-G-BT is a high-precision digital indicating torque screwdriver engineered for quality inspections, precise torque verification, and controlled tightening in demanding assembly environments such as electronics manufacturing, automotive component installation, and precision instrumentation. Delivering accurate measurements from 40 to 200 cN·m via a 1/4" hex drive, this electric tool features a digital display for real-time torque readout, an LED illuminating ring for immediate pass/fail judgments, and Bluetooth connectivity for wireless data management alongside USB output. Lightweight and ergonomic with a reversible torque indication direction for flexible work postures, it supports bi-directional operation (clockwise and counterclockwise) for versatile use in tightening and loosening tasks, promoting operator efficiency and reducing the risk of over-torquing in low-force applications.
