Features and benefits
- Wera's adjustable torque screwdrivers allow variable torque settings with maximum precision and ensure that the user gets the very best results in the familiar Wera design with superior ergonomics.
- The requirements for ESD-safe screwdrivers are specified in the European standard DIN EN 61340-5-1. This standard also includes a handle that has to be out of a defined conductive material. The Wera products in the ESD series satisfy these standards and the even more stringent requirements demanded by some technology companies.
- Simple setting of the required torque by hand.
- Easy-to-read scale value.
- Articles 7430, 7431 and 7432 all come with a magnifying glass. This can be easily attached on to the scale, dramatically improving visibility.
- Measurement accuracy is ± 6 % (article 1430: ± 10 %) in accordance with the standard DIN EN ISO 6789. Distinctly audible and noticeable excess-load signal when the pre-set torque is reached.
- Unlimited torque for loosening seized screws.
- Rapidaptor technology makes the tool adaptable since bits and sockets can be exchanged rapidly.
