The Norbar Torque Screwdriver is accurate, comfortable, durable and easy-to-use. Its accuracy exceeds the minimal requirements of ISO, The International Organisation for Standardisation 6789:2017 (±6% for tools up to 10Nm).
It is supplied with a 1/4in hexagon bit holder designed using a 4mm hexagon stem. It comes supplied with a traceable calibration certificate (for the clockwise direction). The comfortable, durable handle is constructed using 2 materials; a base material for strength, overlaid with a soft feel grip for comfort and slip resistance.
The screwdriver allows for easy torque adjustment without the need of additional specialist tools and also has a lock to prevent accidental adjustment of the set torque.
