The Norbar Torque Screwdriver is accurate, comfortable, durable, and easy to use. Supplied with a 1/4in hexagon bit holder. The comfortable, durable handle is constructed using two materials; a base material for strength overlaid with a soft feel grip for comfort and slip resistance. For maximum versatility and particularly for applications with limited access, the bit holder can be removed and replaced with widely available screwdriver blades. 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. The tool slips when torque is achieved, removing the possibility of over tightening. It comes supplied with a traceable calibration certificate (for the clockwise direction).
