The Wiha electric Torque Wrench is built with two directions of rotation, ideal for powerful, yet controlled tightening. The user can pull out and turn the handle end to set the required torque value manually by looking at the numeric scale. In addition, the ball fastener provides a secure hold for the nut drivers. Easy to use thanks to a noticeable snap back on the torque mechanism in the key when the preset torque value is reached. Its 10° switching angle is great for fastening components onto bus bars in junction boxes. Individually tested as per the international IEC 60900 standard, allowing users to work safely on live parts up to 1, 000 V AC. This torque wrench can only be used in combination with insulated Wiha nut driver inserts. Specifications: Drive: 1/4in. Accuracy: ± 4%. Torque range: 5-25Nm. Length : 288mm. Weight: 590g.
